This causes severe performance degradation > on multi-tenant clusters with thousands of databases (very similar to how the > old get_function() metastore call didn't scale). > We should add a metastore call which can retrieve all materialized view > definitions at once (for all DBs) so that we don't have to make thousands of > metastore calls per query. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
