-----------------------------------------
Please find links to the code which is used to list files recursively if you
need to investigate further.

> Key: DRILL-7004
> URL: https://issues.apache.org/jira/browse/DRILL-7004
> Project: Apache Drill
> Issue Type: Wish
> Components: Storage - Other
> Affects Versions: 1.15.0
> Reporter: benj
> Priority: Major
>
> For instant, it's possible to show files/directories in a particular
> directory with the command
> {code:java}
> SHOW files FROM tmp.`mypath`;
> {code}
> It would be certainly very useful to improve this functionality with :
> * possibility to list recursively
> * possibility to use at least wildcard
> {code:java}
> SHOW files FROM tmp.`mypath/*/test/*/*a*`;
> {code}
> * possibility to use the result like a table
> {code:java}
> SELECT p.* FROM (SHOW files FROM tmp.`mypath`) AS p WHERE ...
> {code}
