Vitalii Diravka resolved DRILL-5192.
------------------------------------
Resolution: Won't Fix
Assignee: Vitalii Diravka
[~bgajjela] Once you perform the query and the data is changed after last
{{REFRESH TABLE}}, the metadata cache files are regenerated automatically. No
need to perform {{REFRESH METADATA TABLE}}.
See details in
[docs|https://drill.apache.org/docs/optimizing-parquet-metadata-reading/#generating-the-parquet-metadata-cache-file]
and
[code|https://github.com/apache/drill/blob/master/exec/java-exec/src/main/java/org/apache/drill/exec/store/parquet/metadata/Metadata.java#L642].
Also the new "Metadata Management" work aka "Drill Metastore" is in progress.
If you have suggestions, please put them in DRILL-6552
