Configuring the Filestore

Overview

The filestore is where binaries are physically stored. It is part of the two stores essential for Artifactory's storage and management resources.

JFrog Artifactory offers flexible filestore management through the binarystore.xml configuration file located in the $JFROG_HOME/artifactory/var/etc/artifactory folder. By modifying this file you can implement a variety of different storage configurations.

These include basic and customizable local and network based file-systems, cloud storage, as well as redundant storage.

In addition to using different storage providers, you can also chain a series of storage providers together to build complex and scalable binary storage setups.

Take care when modifying binarystore.xml

Making changes to this file may result in losing binaries stored in Artifactory!

If you are not sure of what you are doing, please contact JFrog Support for assistance.

Binary Provider

A binary provider is a storage element that is based on checksum-based storage system. This page will describe how to use one or more of these providers. For example, a "cached filesystem".

Chains and Binary Providers

The binarystore.xml file can include a chain with a set of binary providers. These pre-defined sets of storage configurations are intended to create a common storage config.

Binary providers can be embedded into one another to form chains that represent a coherent filestore. Artifactory comes with a built-in set of chains that correspond to the binary.provider.type parameter that was used in previous versions of Artifactory. The built-in set of chains available in Artifactory are:

file-system
cache-fs
full-db
full-db-direct
s3
google-storage
double-shards
redundant-shards
cluster-file-system
cluster-s3
cluster-google-storage
cluster-azure-blob-storage

Page contents

Getting Started

Artifactory includes the following default binarystore.xml configuration:

<config version="v1">
	<chain template="file-system"/>
</config>

<config> The wrapper element containing a chain element. The binarystore.xml must must start and end with this element.
<chain template> The structure of the filestore. To use one of the built-in filestores, the chain element needs to include the corresponding template attribute.

Version Attribute

Note that the the <config> tag is a marker element for versioning configs. It does not affect Artifactory's settings:

<config version="v1">
…
</config>

Chain Templates

The following sections describe the basic chain templates come built-in with Artifactory and are ready for you to use out-of-the-box, as well as other binary providers that are included in the default chains.

Additional information about every template can be found below, under the Built-in Chain Templates section.

file-system	The most basic filestore configuration for Artifactory used for a local or mounted filestore.
cache-fs	Works the same way as filesystem but also caches download requests that are cleaned up using an LRU (Least Recently Used) protocol. Improves performance of instances with high IOPS (I/O Operations) or slow NFS access.
full-db	All the metadata and the binaries are stored as BLOBs in the database with an additional layer of caching.
full-db-direct	All the metadata and the binaries are stored as BLOBs in the database without caching.
s3	This is the setting used for S3 Object Storage using the JetS3t library.
s3Old	This is the setting used for S3 Object Storage using JCloud as the underlying framework.
google-storage	This is the setting used for Google Cloud Storage as the remote filestore.
azure-blob-storage	This is the setting used for Azure Blob Storage as the remote filestore.
double-shards	A pure sharding configuration that uses 2 physical mounts with 1 copy (which means each artifact is saved only once).
redundant-shards	A pure sharding configuration that uses 2 physical mounts with 2 copies (which means each shard stores a copy of each artifact).
cluster-file-system	A filestore configuration where each node has its own local filestore (just like the file-system chain) and is connected to all other nodes via dynamically allocated Remote Binary Providers using the Sharding-Cluster provider.
cluster-s3	This is the setting used for S3 Object Storage using the JetS3t library. It is based on the sharding and dynamic provider logic that synchronizes the cluster-file-system.
cluster-google-storage	This is the setting used for Google Cloud Storage using the JetS3t library. It is based on the sharding and dynamic provider logic that synchronizes the cluster-file-system.
cluster-azure-blob-storage	This is the setting used for Azure Blob Storage. It is based on the sharding and dynamic provider logic that synchronizes the cluster-file-system.

Modifying an Existing Chain Template

To accommodate any specific requirements you may have for your filestore, you may modify one of the existing chain templates either by extending it with additional binary providers or by overriding one of its attributes. For example, the built-in filesystem chain template stores binaries under the $JFROG_HOME/artifactory/var/data/artifactory/filestore directory.

To modify the template so that it stores binaries under $FILESTORE/binaries you could extend it as follows:

<!-- file-system chain template structure  -->  
<config version="v1">   
	<chain template="file-system"/>
	<provider id="file-system" type="file-system"> 				<!-- Modify the "file-system" binary provider -->
		<baseDataDir>$FILESTORE/binaries</baseDataDir>		<!-- Override the <baseDataDir> attribute -->
	</provider>
</config>

Built-in Chain Templates

Artifactory comes with a set of chain templates built-in allowing you to set up a variety of different filestores out-of-the-box. However, to override the built-in filestores, you need to be familiar with the attributes available for each binary provider that is used in them. These are described in the following sections which also show the template configuration and what is 'under the hood' in each template. Also, usage examples can be found for all templates.

Filesystem Binary Provider

This is the basic filestore configuration for Artifactory and is used for a local or mounted filestore.

file-system template configuration

If you choose to use the file-system template, your binarystore.xml configuration file should look like this:

<config version="v1">
	<chain template="file-system"/>
</config>

What's in the template?

While you don't need to configure anything else in your binarystore.xml, this is what the file-system template looks like under the hood.

In this example, the filestore and temp folder are located under the root directory of the machine.

<config version="v1">
	<chain template="file-system"/>
	<provider id="file-system" type="file-system">
		<baseDataDir>/var/opt/jfrog/data</baseDataDir>
        <fileStoreDir>/filestore</fileStoreDir>   
		<tempDir>/temp</tempDir>
	</provider>
</config>

Where:

type	file-system
baseDataDir	Default: `$JFROG_HOME/artifactory/var/data/artifactory` The root directory where Artifactory should store data files.
fileStoreDir	Default: `filestore` The root folder of binaries for the filestore. If the value specified starts with a forward slash (“/”) the value is considered the fully qualified path to the filestore folder. Otherwise, it is considered relative to the baseDataDir.
tempDir	Default: `temp` A temporary folder under baseDataDir into which files are written for internal use by Artifactory. This must be on the same disk as the fileStoreDir.

Cached Filesystem Binary Provider

The cache-fs serves as a binary cache that uses LRU (Least Recently Used) as its cleanup protocol. This can improve Artifactory's performance since frequent requests will be served from the cache-fs (as in case of the S3 binary provider).

The cache-fs binary provider will be the closest filestore layer of Artifactory. This means that if the filestore is mounted, we would like the cache-fs to be local on the artifactory server itself (if the filestore is local, then cache-fs is meaningless). In the case of an HA configuration, the cache-fs will be mounted and the recommendation is for each node to have its own cache-fs layer.

cache-fs template configuration

If you choose to use the cache-fs template, your binarystore.xml configuration file should look like this:

<config version="v1">
	<chain template="cache-fs"/>
</config>

What's in the template?

While you don't need to configure anything else in your binarystore.xml, this is what the cache-fstemplate looks like under the hood.

This example sets the cache-fs size to be 10GB and its location (absolute path since it starts with a "/") to be /cache/filestore.

<config version="v1">
	<chain template="cache-fs"/>
	<provider id="cache-fs" type="cache-fs">
    	<cacheProviderDir>/cache/filestore</cacheProviderDir>
		<maxCacheSize>10000000000</maxCacheSize>
	</provider>
</config>

Where:

type	cache-fs
maxCacheSize	Default: 5000000000 (5GB) The maximum storage allocated for the cache in bytes. Please note that maxCacheSize does not include files that are in progress of being uploaded (which is saved under cache/_pre); thus it is recommended to keep extra spaces for _pre folder.
cacheProviderDir	Default: cache The root folder of binaries for the filestore cache. If the value specified starts with a forward slash (“/”) it is considered the fully qualified path to the filestore folder. Otherwise, it is considered relative to the baseDataDir.

Cloud Storage Providers

Cloud Object Storage Support

JFrog Container Registry and Artifactory Pro support using cloud object storage from the major SaaS providers including Amazon's S3, Google's Cloud Storage, or Azure's Blob Storage as their binary provider.
An Enterprise license is required for other object storage providers, such as OpenStack Swift or NetApp's StorageGRID.

As part of its universal approach, Artifactory supports a variety of cloud storage providers described in detail in the sections below. These providers will typically be wrapped with other binary providers to ensure that the binary resources are always available from Artifactory (for example, to enable Artifactory to serve files when requested even if they have not yet reached the cloud storage due to upload latency).

High Availability clusters will need to use a shared mount for the S3 provider

Using the S3 storage provider (or the S3chain template), will require a shared mount for cluster. This is since only the primary node will handle the object store interaction, while all of the nodes, will be able to add files to the shared mount eventual directory.

An alternative to using the S3 provider for clusters without a shared mount, would be to use the cluster-s3 chain template.

Amazon S3 Official SDK Template

From version 6.12, Artifactory provides the following s3-storage-v3 template to configure your S3 Cloud Storage using the official Amazon SDK.

Authentication Mechanism

The following authentication methods are supported:

Basic credentials
Default Amazon Provider Chain credentials. The default Amazon Provider chain searches for credentials in this order:

1. System property based credentials
2. Credentials profiles file.
3. Credentials delivered through the Amazon EC2 container service.
4. Instance profile credentials delivered through the Amazon EC2 metadata service.

The Amazon S3 Official Amazon SDK template is used for configuring S3 Cloud Storage and supports the following set of parameters.

type	s3-storage-v3
testConnection	Default: true When set to true, the binary provider uploads and downloads a file when Artifactory starts up to verify that the connection to the cloud storage provider is fully functional.
identity	Your cloud storage provider identity.
credential	Your cloud storage provider authentication credential.
region	The region offered by your cloud storage provider with which you want to work.
bucketName	Your globally unique bucket name.
path	Default: filestore The path relative to the bucket where binary files are stored.
rootFoldersNameLength	Default: 2 The number of initial characters in the object's checksum that should be used to name the folder in storage. This can take any value between 0 - 5. 0 means that checksum files will be stored at the root of the object store bucket. For example, if the object's checksum is 8c335149... and `rootFoldersNameLength` is set to 4, the folder under which the object would be stored would be named 8c33.
proxyIdentity	Corresponding parameters if you are accessing the cloud storage provider through a proxy server.
proxyCredential
proxyPort
proxyHost
endPoint	The cloud storage provider’s URL.
kmsServerSideEncryptionKeyId	Default=N/A. Only applies to the s3-storage-v3 template. Use KMS Encryption client with given KMS encryption key ID or alias.
kmsCryptoMode	Default: EncryptionOnly. Only applies to the s3-storage-v3 template. Use KMS encryption with one of the following crypto policies: EncryptionOnly AuthenticatedEncryption StrictAuthenticatedEncryption For more information, see https://docs.aws.amazon.com/sdk-for-java/v1/developer-guide/examples-crypto-kms.html.
useInstanceCredentials	Default: false. When true, use AWS S3 default provider chain according to the Authentication mechanism.
usePresigning	Default: false. When set to true, applies to signed URLs for adding, deleting, getting client methods on s3 objects.
multiPartLimit	Default: 100,000,000 bytes When usePresigning is set to false, or for the s3old and s3 templates File size threshold (in bytes) over which file uploads are chunked and multi-threaded.
transferManagerThreads	Default: 10. Only applies to the s3-storage-v3 template. Applies when usePresigning is set to false Applies to multipart uploads, configured by the multiPartLimit.
signatureExpirySeconds	Default: 300 Sets the validity period in seconds for signed URLs used internally for uploads and downloads.
maxConnections	Default: 50. Sets the maximum HTTP client connections for the AWS client
connectionTimeout	Default: 10x1000. Sets the connection timeout (in milliseconds) for the AWS client.
socketTimeout	Default: 50 * 1000. Sets the socket timeout (in milliseconds) for the AWS client.
enablePathStyleAccess	Default: false Amazon S3 supports virtual-hosted-style and path-style access in all regions. The path-style syntax requires that using the region-specific endpoint when attempting to access a bucket. For non-AWS users, this property may need to be set to true.
disableChunkedEncoding	Default: false The default behavior is to enable chunked encoding automatically for PutObjectRequest and UploadPartRequest. Setting this flag will result in disabling chunked encoding for all requests, which may impact performance. Using this option is recommended only if your endpoint does not implement chunked uploading.
useDeprecatedBucketExistenceCheck	Default: false Setting this property will force checking bucket existence based on a HEAD request to the bucket. (Deprecated in AWS)

The snippets below show the basic template configuration and examples that use the S3 binary provider to support several configurations (CEPH, CleverSafe and more).

s3 Binary Storage template configuration

Because you must configure the s3 provider with parameters specific to your account (but can leave all other parameters with the recommended values), if you choose to use this template, your binarystore.xml configuration file should look like this:

What's in the template?

<chain template="s3-storage-v3">
   <provider id="cache-fs" type="cache-fs">
       <provider id="eventual" type="eventual">
           <provider id="retry" type="retry">
               <provider id="s3-storage-v3" type="s3-storage-v3"/>
           </provider>
       </provider>
   </provider>
</chain>

While you don't need to configure anything else in your binarystore.xml, this is what the s3-storage-v3 template may look like under the hood.

This example sets the s3 with your credentials, use pre-signing for object manipulations and sets the pre signed URL for 10 minutes (600 seconds)

<config version="2">
   <chain template="s3-storage-v3"/>
   <provider id="s3-storage-v3" type="s3-storage-v3">
       <endpoint>http://s3.amazonaws.com</endpoint>
       <bucketName>bucketName</bucketName>
       <path>pathPrefix</path>
       <region>s3Region</region>
       <identity>yourIdentity</identity>
       <credential>yourCredentials</credential>
       <usePresigning>true</usePresigning>
       <signatureExpirySeconds>600</signatureExpirySeconds>
   </provider>
</config>

S3 Binary Provider

Artifactory provides the following templates to configure your storage on an S3 cloud provider:

The s3 template: Used for configuring S3 Object Storage using the JetS3t library.
The s3Old template: Used for configuring S3 Object Storage using the JClouds.

Newest recommended version of the S3 template

From version 6.12, Artifactory supports configuring S3 Object Storage using the official Amazon SDK. For additional information, see the s3-storage-v3 template.

type	s3 or s3old
testConnection	Default: true When set to true, the binary provider uploads and downloads a file when Artifactory starts up to verify that the connection to the cloud storage provider is fully functional.
multiPartLimit	Default: 100,000,000 bytes File size threshold over which file uploads are chunked and multi-threaded.
identity	Your cloud storage provider identity.
credential	Your cloud storage provider authentication credential.
region	The region offered by your cloud storage provider with which you want to work.
bucketName	Your globally unique bucket name.
path	Default: filestore The path relative to the bucket where binary files are stored.
rootFoldersNameLength	Default: 2 The number of initial characters in the object's checksum that should be used to name the folder in storage. This can take any value between 0 - 5. 0 means that checksum files will be stored at the root of the object store bucket. For example, if the object's checksum is 8c335149... and `rootFoldersNameLength` is set to 4, the folder under which the object would be stored would be named 8c33.
proxyIdentity	Corresponding parameters if you are accessing the cloud storage provider through a proxy server.
proxyCredential
proxyPort
proxyHost
port	The cloud storage provider’s port.
endPoint	The cloud storage provider’s URL.
roleName	Only available on S3. The IAM role configured on your Amazon server for authentication. When this parameter is used, the refreshCredentials parameter must be set to true.
refreshCredentials	Default: false. Only available on S3. When true, the owner's credentials are automatically renewed if they expire. When roleName is used, this parameter must be set to true.
httpsOnly	Default: true. Only available on S3. Set to true if you only want to access your cloud storage provider through a secure https connection.
httpsPort	Default: 443. Must be set if httpsOnly is true. The https port for the secure connection. When this value is specified, the port needs to be removed from the endPoint.
providerID	Set to S3. Only available for S3old.
s3AwsVersion	Default: 'AWS4-HMAC-SHA256' (AWS signature version 4). Only available on S3. Can be set to 'AWS2' if AWS signature version 2 is needed. Please refer the AWS documentation for more information.
<property name="s3service.disable-dns-buckets" value="true"></property>	Artifactory by default prepends the bucketName in front of the endpoint (e.g. mybucket.s3.aws.com) to create an URL that it access the S3 bucket with. S3 providers such as Amazon AWS uses this convention. However, this is not the case for some S3 providers use the bucket name as part of the context URL (e.g. s3provider.com/mybucket); so Artifactory needs to have following parameter added in order for the URI to be compatible with the S3 providers. S3 providers that use this URI format includes OpenStack, CEPH, CleverSafe, and EMC ECS.
<property name="s3service.server-side-encryption" value="aws:kms"></property>	Use this property to set up Artifactory to work with against an S3 bucket configured with a KMS encryption key.
signedURLExpirySeconds	Default: 30 Specifies the number of seconds that a signed URL provided to a requesting client for direct download from cloud storage is valid.

The snippets below show the basic template configuration and examples that use the S3 binary provider to support several configurations (CEPH, CleverSafe and more).

s3 template configuration

Google Storage Binary Provider Native Client Template

The google-storage-v2 template is used for configuring Google Cloud Storage as the remote filestore using the Google native client.

Authentication Mechanism

Authentication is established using a credentials file generated automatically by Google.

Authentication Resolution Order

We support three methods for resolving

The authentication resolution order follows:

‘useInstanceCredentials’ == true && set the "GOOGLE_APPLICATION_CREDENTIALS" env var
‘useInstanceCredentials’ == true && use Kubernetes (or other) service account creds (no creds file)
‘useInstanceCredentials’ == false && save creds file under the default path [arti_home_full_path]/etc/gcp.credentials.json.
Grant the "Cloud Functions Service Agent" role to the utilized service account in order to use the instance's credentials.
Artifactory searches for an environment variable named GOOGLE_APPLICATION_CREDENTIALS containing the path to the credentials file. If the environment variable does not exist, the default service account provided by the Compute Engine, Kubernetes Engine, App Engine, and Cloud Functions will be applied to applications running on those services.

The snippets below show the basic google-storage-v2 template configuration and examples that use the Google Cloud Storage binary provider.

This binary provider uses the following set of parameters:

type	google-storage-v2
bucketName	Your globally unique bucket name.
path	Default: filestore Sets the path relative to the bucket where binary files are stored.
rootFoldersNameLength	Default: 2. The number of initial characters in the object's checksum that should be used to name the folder in storage. This can take any value between 0 - 6. 0 means that checksum files will be stored at the root of the object store bucket. For example, if the object's checksum is 8c335149... and `rootFoldersNameLength` is set to 4, the folder under which the object would be stored would be named 8c33.
bucketExists	Default: false. When set to true, it indicates to the binary provider that a bucket already exists in Google Cloud Storage and therefore does not need to be created.
testConnection	Default: true When set to true, the binary provider uploads and downloads a file when Artifactory starts up to verify that the connection to the cloud storage provider is fully functional.
useInstanceCredentials	Default: false. When set to true use, the "GOOGLE_APPLICATION_CREDENTIALS" environment variable finds the credentials or uses the default service account. When set to false, the default path is used to find the credentials file.
enableSignedUrlRedirect	Default: false. When set to true, redirecting download requests using enabled signed URLs.
signedUrlExpirySeconds	Default: 30. Sets the signed URL validity period in seconds.
signatureExpirySeconds	Default: 30. Specifies the number of seconds that a signed URL used internally for upload/download is valid.
proxyIdentity	Default: No proxy Corresponding parameters if you are accessing the cloud storage provider through a proxy server.
proxyCredential
proxyPort
proxyHost
maxConnections	Default: 100 Sets the maximum http client connections.
ConnectionTimeout	Sets the connections timeout.

Eventual Binary Provider

This binary provider is not independent and will always be used as part of a template chain for a remote filestore that may exhibit upload latency (e.g. S3 or GCS). To overcome potential latency, files are first written to a folder called “eventual” under the baseDataDir in local storage, and then later uploaded to persistent storage with the cloud provider. The default location of the eventual folder is under the $JFROG_HOME/artifactory/data/artifactory folder (or $CLUSTER_HOME/ha-data in the case of an HA configuration using a version of Artifactory below 5.0) and is not configurable. You need to make sure that Artifactory has full read/write permissions to this location.

There are three additional folders under the eventual folder:

_pre: part of the persistence mechanism that ensures all files are valid before being uploaded to the remote filestore
_add: handles upload of files to the remote filestore
_delete: handles deletion of files from the remote filestore

Example

The example below shows a configuration that uses S3 for persistent storage after temporary storage with an eventual binary provider. The eventual provider configures 10 parallel threads for uploading and a lock timeout of 180 seconds.

<!-- The S3 binary provider configuration -->
<config version="v1">
	<chain template="s3"/>
	<provider id="s3" type="s3">
    	<identity>XXXXXXXXX</identity>
		<credential>XXXXXXXX</credential>     
		<endpoint><My OpenStack Server></endpoint>
		<bucketName><My OpenStack Container></bucketName>
		<httpsOnly>false</httpsOnly> 
    	<property name="s3service.disable-dns-buckets" value="true"></property>                               
	</provider>
 
<!-- The eventual provider configuration -->
	<provider id="eventual" type="eventual">
		<numberOfThreads>10</numberOfThreads>	
		<timeout>180000</timeout>
	</provider>
</config>

Where:

type	eventual
timeout	The maximum amount of time a file may be locked while it is being written to or deleted from the filesystem.
dispatcherInterval	Default: 5000 ms The interval between which the provider scans the “eventual” folder to check for files that should be uploaded to persistent storage.
numberOfThreads	Default: 5 The number of parallel threads that should be allocated for uploading files to persistent storage.

Retry Binary Provider

This binary provider is not independent and will always be used as part of a more complex template chain of providers. In case of a failure in a read or write operation, this binary provider notifies its underlying provider in the hierarchy to retry the operation.

type	retry
interval	Default: 5000 ms The time interval to wait before retries.
maxTrys	Default: 5 The maximum number of attempts to read or write before responding with failure.

Example

The example below shows a configuration that uses S3 for persistent storage , but uses a retry provider to keep retrying (up to a maximum of 10 times) in case upload fails.

<!-- The S3 binary provider configuration -->
<config version="v1">
	<chain template="s3"/>
	<provider id="s3" type="s3">
    	<identity>XXXXXXXXX</identity>
	   	<credential>XXXXXXXX</credential>     
	   	<endpoint><My OpenStack Server></endpoint>
	   	<bucketName><My OpenStack Container></bucketName>
	   	<httpsOnly>false</httpsOnly> 
    	<property name="s3service.disable-dns-buckets" value="true"></property>                               
	</provider>

<!-- The retry provider configuration -->
	<provider id="retry" type="retry">
		<maxTrys>10</maxTrys>
	</provider>
</config>

Sharding Binary Provider

Artifactory offers a Sharding Binary Provider that lets you manage your binaries in a sharded filestore. A sharded filestore is one that is implemented on a number of physical mounts (M), which store binary objects with redundancy (R), where R <= M.
This binary provider is not independent and will always be used as part of a more complex template chain of providers. To learn about sharding, refer to Filestore Sharding.

type	sharding
lenientLimit	Default: 1 (From version 5.4. Note that for filestores configured with a custom chain and not using the built-in templates the default value of the `lenientLimit` parameter is 0 to maintain consistency with previous versions.) Theminimumnumber of successful writes thatmust be maintained for an upload to be successful. The next balance cycle (triggered with the GC mechanism) will eventually transfer the binary to enough nodes such that the redundancy commitment is preserved. In other words, Leniency governs the minimal allowed redundancy in cases where the redundancy commitment was not kept temporarily. For example, if`lenientLimit`is set to 3, my setup includes 4 filestores, and 1 of them goes down, writing will continue. If a 2nd filestore goes down, writing will stop. The amount of currently active nodes must always be greater or equal than the configured lenientLimit. If set to 0, the redundancy value has to be kept.
readBehavior	This parameter dictates the strategy for reading binaries from the mounts that make up the sharded filestore. Possible values are: roundRobin (default): Binaries are read from each mount using a round robin strategy.
writeBehavior	This parameter dictates the strategy for writing binaries to the mounts that make up the sharded filestore. Possible values are: roundRobin (default):Binaries are written to each mount using a round robin strategy. freeSpace: Binaries are written to the mount with the greatest absolute volume of free space available. percentageFreeSpace: Binaries are written to the mount with the percentage of free space available.
redundancy	Default: r = 1 The number of copies that should be stored for each binary in the filestore. Note that redundancy must be less than or equal to the number of mounts in your system for Artifactory to work with this configuration.
concurrentStreamWaitTimeout	Default: 30,000 ms To support the specified redundancy, accumulates the write stream in a buffer, and uses “r” threads (according to the specified redundancy) to write to each of the redundant copies of the binary being written. A binary can only be considered written once all redundant threads have completed their write operation. Since all threads are competing for the write stream buffer, each one will complete the write operation at a different time. This parameter specifies the amount of time (ms) that any thread will wait for all the others to complete their write operation. If a write operation fails, you can try increasing the value of this parameter.
concurrentStreamBufferKb	Default: 32 Kb The size of the write buffer used to accumulate the write stream before being replicated for writing to the “r” redundant copies of the binary. If a write operation fails, you can try increasing the value of this parameter.
maxBalancingRunTime	Default: 3,600,000 ms (1 hour) Once a failed mount has been restored, this parameter specifies how long each balancing session may run before it lapses until the next Garbage Collection has completed. For more details about balancing, please refer to Using Balancing to Recover from Mount Failure. To restore your system to full redundancy more quickly after a mount failure, you may increase the value of this parameter. If you find this causes an unacceptable degradation of overall system performance, you can consider decreasing the value of this parameter, but this means that the overall time taken for Artifactory to restore full redundancy will be longer.
freeSpaceSampleInterval	Default: 3,600,000 ms (1 hour) To implement its write behavior, Artifactory needs to periodically query the mounts in the sharded filestore to check for free space. Since this check may be a resource intensive operation, you may use this parameter to control the time interval between free space checks. If you anticipate a period of intensive upload of large volumes of binaries, you can consider decreasing the value of this parameter in order to reduce the transient imbalance between mounts in your system.
minSpareUploaderExecutor	Default: 2 Artifactory maintains a pool of threads to execute writes to each redundant unit of storage. Depending on the intensity of write activity, eventually, some of the threads may become idle and are then candidates for being killed. However, Artifactory does need to maintain some threads alive for when write activities begin again. This parameter specifies the minimum number of threads that should be kept alive to supply redundant storage units.
uploaderCleanupIdleTime	Default: 120,000 ms (2 min) The maximum period of time threads may remain idle before becoming candidates for being killed.

State-Aware Binary Provider

This binary provider is not independent and will always be used in the sharding or sharding-cluster providers. Theprovider is aware if its underlying disk is functioning or not. It is identical to the basic filesystem provider provider, however, it can also recover from errors (the parent provider is responsible for recovery) with the addition of the checkPeriod field.

type	state-aware
checkPeriod	Default: 15000 ms The minimum time to wait between trying to re-activate the provider if it had fatal errors at any point.
writeEnabled	Default: true From Artifactory 6.18 and later, enables/disables the write operations for the binary provider. If set to false, the state-aware provider will continue to serve read requests, so Artifactory can continue to read binaries from that provider. In addition, the garbage collection can continue to clean the deleted binaries from the provider. (Only applicable under a sharding provider.)
zone	The name of the sharding zone the provider is part of (only applicable under a sharding provider)

Configuring Sharding for HA Cluster

These binary providers are only available with an Enterprise license.

For a High Availability cluster, Artifactory offers templates that support sharding-cluster for File-System, S3 and Google Storage. To learn more about the different sharding capabilities, refer to Filestore Sharding.
When configuring your filestore on an HA cluster, you need to place the binarystore.xml under $JFROG_HOME/artifactory/var/etc/artifactory in the primary node and it will be synced to the other members in the cluster.

File System Cluster Binary Provider

When using the cluster-file-system template, each node has its own local filestore (just like in the file-system binary provider) and is connected to all other cluster nodes via dynamically allocated Remote Binary Providers using the Sharding-Cluster Binary Provider.

cluster-file-system template configuration

If you choose to use the cluster-file-system template, your binarystore.xml configuration file should look like this:

<config version="2">

This is the setting used for Google Cloud Storage using the JetS3t library when configuring filestore sharding for an HA cluster. It is based on the sharding and dynamic provider logic that synchronizes the cluster-file-system.
When using the cluster-google-storage template, data is temporarily stored on the file system of each node using the Eventual Binary Provider, and is then passed on to your Google storage for persistent storage.
Each node has its own local filestore (just like in the file-system binary provider) and is connected to all other cluster nodes via dynamically allocated Remote Binary Providers using the Sharding-Cluster Binary Provider.

cluster-google-storage template configuration

Because you must configure the google-storage provider with parameters specific to your account (but can leave all other parameters with the recommended values), if you choose to use the cluster-google-storage template, your binarystore.xml configuration file should look like this:

<config version="2">
	<chain template="cluster-google-storage"/>
	<provider id="google-storage" type="google-storage">
		<endpoint>commondatastorage.googleapis.com</endpoint>
		<bucketName><BUCKET NAME></bucketName>
		<identity>XXXXXX</identity>
		<credential>XXXXXXX</credential>
	</provider>
</config>

What's in the template?

While you don't need to configure anything else in your binarystore.xml, this is what the cluster-google-storage template looks like under the hood.

<config version="2">
	<chain> <!--template="cluster-google-storage"-->
    	<provider id="cache-fs-eventual-google-storage" type="cache-fs">
        	<provider id="sharding-cluster-eventual-google-storage" type="sharding-cluster">

Azure Blob Storage Cluster Binary Provider

This is the setting used for Azure Blob Storage. It is based on the sharding and dynamic provider logic that synchronizes the cluster-file-system.
When using the cluster-azure-blob-storage template, data is temporarily stored on the file system of each node using the Eventual Binary Provider, and is then passed on to your Azure Blob Storage for persistent storage.
Each node has its own local filestore (just like in the file-system binary provider) and is connected to all other cluster nodes via dynamically allocated Remote Binary Providers using the Sharding-Cluster Binary Provider.

cluster-azure-blob-storage template configuration

Because you must configure the azure-blob-storage provider with parameters specific to your account (but can leave all other parameters with the recommended values), if you choose to use the cluster-azure-blob-storage template, your binarystore.xml configuration file should look like this:

<config version="2">
	<chain template="cluster-azure-blob-storage"/>
    <provider id="azure-blob-storage" type="azure-blob-storage">
        <accountName>XXXXXX</accountName>
        <accountKey>XXXXXX</accountKey>
        <endpoint>https://<ACCOUNT_NAME>.blob.core.windows.net/</endpoint>

Sharding-Cluster Binary Provider

The sharding-cluster binary provider can be used together with other binary providers for both local or cloud-native storage. It adds a crossNetworkStrategy parameter to be used as read and write behaviors for validation of the redundancy values and the balance mechanism. It must include a Remote Binary Provider in its dynamic-provider setting to allow synchronizing providers across the cluster.

The Sharding-Cluster provider listens to cluster topology events and creates or removes dynamic providers based on the current state of nodes in the cluster.

type	sharding-cluster
zones	The zones defined in the sharding mechanism. Read/write strategies take providers based on zones.
lenientLimit	Default: 1 (From version 5.4. Note that for filestores configured with a custom chain and not using the built-in templates, the default value of the lenientLimit parameter is 0 to maintain consistency with previous versions.) The maximum number of filestores that can be unreachable for writes to continue. For example, if `lenientLimit` is set to 2, my setup includes 4 filestores, and 2 of them go down, writing will continue. If a 3rd filestore goes down, writing will stop. lenientLimit must be less than the total Redundancy. (Active Nodes ≥ Redundancy - LenientLimit) Typically this is used to address transient failures of an individual binary store, with the assumption that the balance mechanism will make up for it over time.
dynamic-provider	The type of provider that can be added and removed dynamically based on cluster topology changes. Currently only the Remote Binary Provider is supported as a dynamic provider.

Example

<config version="v1">
	<chain>
    	<provider id="cache-fs" type="cache-fs">    
			<provider id="sharding-cluster" type="sharding-cluster">
				<sub-provider id="state-aware" type="state-aware"/>
			 	<dynamic-provider id="remote" type="remote"/>
			 	<property name="zones" value="remote"/>
			</provider>
		</provider>
	</chain>
 
	<provider id="sharding-cluster" type="sharding-cluster">
		<readBehavior>crossNetworkStrategy</readBehavior>
 		<writeBehavior>crossNetworkStrategy</writeBehavior>
 		<redundancy>2</redundancy>
 		<lenientLimit>1</lenientLimit>
	</provider>
 
  	<provider id="state-aware" type="state-aware">

   	</provider>
 
	<provider id="remote" type="remote">
		<checkPeriod>15000</checkPeriod>
	 	<connectionTimeout>5000</connectionTimeout>
 		<socketTimeout>15000</socketTimeout>

Remote Binary Provider

This binary provider is not independent and will always be used as part of a more complex template chain of providers. In case of a failure in a read or write operation, this binary provider notifies its parent provider in the hierarchy.

The remote Binary Provider links a node to all other nodes in the cluster, meaning it enables each node to 'see' the filestore of every other node.

type	remote
connectionTimeout	Default: 5000 ms Time before timing out an outgoing connection.
socketTimeout	Default: 15000 ms Time before timing out an established connection (i.e. no data is sent over the wire).
maxConnections	Default: 200 Maximum outgoing connections from the provider.
connectionRetry	Default: 2 How many times to retry connecting to the remote endpoint.
zone	The name of the sharding zone the provider is part of (only applicable under a sharding provider).
checkPeriod	Default: 15000 ms The minimum time to wait between trying to re-activate the provider if it had fatal errors at any point.

Example

The following is an example how a remote binary provider may be configured. To see how this can be integrated with a complete binarystore.xml configuration, please refer to the example under Sharding-Cluster Binary Provider.

<provider id="remote" type="remote">
	<checkPeriod>15000</checkPeriod>
 	<connectionTimeout>5000</connectionTimeout>
 	<socketTimeout>15000</socketTimeout>
 	<maxConnections>200</maxConnections>
 	<connectionRetry>2</connectionRetry>
 	<zone>remote</zone>
</provider>

Configuring a Custom Filestore From Scratch

In addition to the built-in filestore chain templates below, you may construct custom chain template to accommodate any filestore structure you need.

Since the different Binary providers in the filestore must be compatible with each other, misconfiguration might lead to data loss. For configuring a custom filestore, please contact JFrog Support.
