You can configure your own database from the following list.
Artifactory supports the following databases.
Microsoft SQL Server
Artifactory HA requires an external database, which is fundamental to management of binaries and is also used to store cluster wide configuration files.
Since Artifactory HA contains multiple Artifactory cluster nodes, your database must be powerful enough to service all the nodes in the system. Moreover, your database must be able to support the maximum number of connections possible from all the Artifactory cluster nodes in your system.
If you are replicating your database you must ensure that at any given point in time all nodes see a consistent view of the database, regardless of which specific database instance they access. Eventual consistency, and write-behind database synchronization is not supported.
