What would it take to support Redis as the datastore to be queried? I know there is an issue for this: https://github.com/metabase/metabase/issues/6145
Isn’t Metabase deeply tied to databases which have SQL interface?
PostgreSQL has a Redis FDW which might have solved this problem but I haven’t looked at it in detail. https://github.com/pg-redis-fdw/redis_fdw
