    Details

      Description

      Currently all Flink meta objects (currently tables only) are stored in memory as part of Calcite catalog. Those objects are temporary (such as inline tables), others are meant to live beyond user session. As we introduce catalog for those objects (tables, views, and UDFs), it makes sense to organize them neatly. Further, having a catalog implementation that store those objects in memory is to retain the currently behavior, which can be configured by user.

      Please note that this implementation is different from the current {{InMemoryExternalCatalog}, which is used mainly for testing and doesn't reflect what's actually needed for Flink meta objects.
