James Turton created DRILL-8057: ----------------------------------- Summary: INFORMATION_SCHEMA filter push down is inefficient Key: DRILL-8057 URL: https://issues.apache.org/jira/browse/DRILL-8057 Project: Apache Drill Issue Type: Improvement Components: Storage - Information Schema Affects Versions: 1.19.0 Reporter: James Turton Fix For: 1.20.0
WHERE clauses in queries against INFORMATION_SCHEMA do not stop Drill from fetching a schema hierarchy from all enabled storage configs. This results in abysmal performance when unresponsive data sources are enabled, as reported by users in the Apache Drill Slack channels. -- This message was sent by Atlassian Jira (v8.20.1#820001)
