Hi,
You could also consider using the JDBC Catalog implementation (via
Postgres) or building your own custom one, see
https://ci.apache.org/projects/flink/flink-docs-master/docs/dev/table/catalogs/#user-defined-catalog
Curious if that would help you out or if you need anything else.
Best regards
I don't think so. As the name tells it is stored "in-memory" which
intrinsically means transient. If you need a persistent catalog you can
use e.g. Hive or Postgres.
You can also try to implement a catalog backed by e.g. a property file.
This could potentially end up in Flink / flink-packages, but
If I understand your question correctly, you're asking if you can
somehow persist the GenericInMemoryCatalog. I am afraid it is not
possible. The idea of the GenericInMemoryCatalog is that it is transient
and is stored purely in memory.
Best,
Dawid
