SELECT * FROM test WHERE c1 = json '{"id":0,"name":"user_0"}';
java.lang.UnsupportedOperationException

When creating a SQLite online store your only option is to create it on the filesystem. As every access needs to hit the filesystem then this slows down the online store.

Describe the solution you'd like
I'd like an option :memory: to use an in memory SQLite store instead. Eg in feature_store.yaml:
