Hi,Is there any documentation available on what the filter capabilities are of the different JDBC data stores, i.e. which functions/operators/etc. are supported for conversion to SQL expressions?
This is quite important to know for people who design app-schema mapping files and filters, because it has a huge effect on performance. But with my recent joining performance increase tool in app-schema, it is also necessary to know this to get it actually to work, because the expressions used for linking features together need to be supported by the filter capabilities to be able to translate it to join statements.
