-----------------------------------
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.
