Artifactory comes with a built-in embedded Derby database that can be reliably used to store data (metadata) for production-level repositories up to hundreds of gigabytes in size.

However, Artifactory supports pluggable database implementations allowing you to change the default to use other popular databases.

Artifactory currently supports the following databases:

For each of the supported databases you can find the corresponding properties file inside $ARTIFACTORY_HOME/misc/db.

Choosing the Right Database

As the default database, Derby provides good performance since it runs in the same process as Artifactory, however, under intensive usage or high load, performance may be degraded since Artifactory and the database compete for shared JVM resources such as caches and memory. Therefore, for Artifactory servers that need to support heavy load, you may consider using an external database such as MySQL or PostgreSQL which are very common choices in many Artifactory installations.

Any of the other supported databases is also a fair choice and may be the practical choice to make if your organization is already using one of them.

Accessing a Remote Database

When using an external database, you need a reliable, stable and low-latency network connection to ensure proper functioning of your system.

When using a fullDB configuration, we strongly recommend a high-bandwidth to accommodate the transfer of large BLOBs over the network.

Modes of Operation

Artifactory supports two modes of operation:

  • Metadata in the database and binaries stored on the file system (This is the default and recommended configuration).
  • Metadata and binaries stored as BLOBs in the database

"Once-And-Only-Once" Content Storage

Artifactory stores binary files only once.

When a new file about to be stored in Artifactory is found to have the same checksum as a previously stored file (i.e. it is identical to a file that has already been stored), Artifactory does not store the new file content, but rather creates a link to the existing file in the metadata of the newly deployed file.

This principle applies regardless of which repository and path artifacts are deployed - you can deploy the same file to many different coordinates, and as long as identical content is found in the storage, it is reused.

Before You Start


Changing the database does not automatically transfer your data to the new database. Please follow the steps below to backup your data so that you can restore it after the change.

Backup Your Current Installation

When changing the database for an existing installation you must import your Artifactory metadata content.

Make sure to backup your current Artifactory system before updating to a new database.

Setup the New Database

To setup your new database you need to perform the following steps:

  • Create a database instance
  • Create an Artifactory user for the database
  • Install the appropriate JDBC driver
  • Copy the relevant database configuration file
  • Configure the corresponding file.

These steps are fully detailed in the specific documentation page for each of the supported databases listed in the Overview.

Advanced Settings

Once you have setup your database, you can configure it to support your expected load with the following two parameters:
The maximum number of pooled database connections (default: 100).
The maximum number of pooled idle database connections (default: 10).
