Pega Platform high availability is database-agnostic. The recommended database features are:
- Highly available clustered databases or third party or database vendor software that supports this feature
- Database fault tolerance that meets production service level agreement requirements — for example, some databases have add-on products to handle failover of hardware or software sub-systems, enabling another piece to take over
For supported database platform versions, see the Platform Support Guide on Pega Community.
- Split schema database architecture
Pega Platform supports a split schema database architecture. The split separates rules and data into separate schemas and is essential for enabling minimal to zero down time during Pega Platform application and strategic application upgrades or patch installation.
- Replicated and split databases
In general, the Pega Platform data can be replicated or split to support high-volume production requirements, reporting, or other needs.
