I would like to have almost all propeties fromspring.sql.init here: username/password (because different users have different permission), maybe platform, and schema-location (in case when users have different from postgresql/maria-db platforms).

Also it would be nice to have ability to set table/schema names, and add ability to grant mermissions on that table to default user (when another username/password specified).

I already have a sketch and can help if you need.

@eddumelendez thanks so much for this improvement! We have just delivered some changes to the ChatMemory API which include the introduction of a ChatMemoryRepository API to separate the two different concerns: memory management strategy and storage mechanism. The JdbcChatMemory has now been superseded by JdbcChatMemoryRepository.

I closed it as duplicate.

We should support to customize platform or schema like BatchProperties.Jdbc, IntegrationProperties.Jdbc, JdbcSessionProperties and QuartzProperties.Jdbc did, WDYT? @eddumelendez
