> 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
> Assignee: Arjun
> Priority: Major
> Fix For: 1.15.0
>
>
> 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.
> 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.
