Arjun created DRILL-6640:
----------------------------
Summary: Drill takes long time in planning when there are large
number of files in views/tables DFS parent directory
Key: DRILL-6640
URL: https://issues.apache.org/jira/browse/DRILL-6640
Project: Apache Drill
Issue Type: Improvement
Components: Query Planning & Optimization
Reporter: Arjun
When Drill is used for querying views/ tables, the query planning time
increases as the number of files in views/tables parent directory increases.
This becomes unacceptably long with complex queries that involve multiple joins
between such views/tables.
This is caused by globStatus operation on view files using GLOB to retrieve
view file status. This can be improved by avoiding the usage of GLOB pattern
for Drill metadata files like view files.
