At the moment, <jdbc:embedded-database /> sets up an embedded database with a minimal set of needed database properties for each supported system, e.g. h2 dbName attribute. But if you want to configure some special database properties for the embedded database, e.g. H2 MVCC support or compatibility mode like Oracle, you would need to add this to the database URL string:
It would be nice if there were some new namespace element like <jdbc:custom-db-properties /> to add these options like in the following configuration example or some other solution where you can specify custom build options for the embedded database, which are applied during construction.
