# Status
Leaving as draft until the following are complete:
- [ ] We need abstract base classes for the catalog and schema providers for
users to implement
- [ ] Verify all combinations of default vs user provided python catalog,
schema, table providers work in unit tests - this is mostly done
- [ ] Add full end-to-end test of registering custom catalog, schema, table
and then do a SQl query against it
