Vitalii Diravka commented on DRILL-6552:
----------------------------------------

[~rhou] Drill will have an API and will have several implementations of 
Metastore. One of them will be HMS. Indeed, it isn't scalable solution. But HMS 
is used by Hive, Spark, Presto and so on. So Drill should have HMS as one of 
the implementations too. It could be the first implementation, but possibly not 
the main one.
Also there is a task in progress - HIVE-9452: Use HBase to store Hive metadata, 
which can solve the scaling issue.

> It would be useful for Drill to have some sort of metastore which would 
> enable Drill to remember previously defined schemata so Drill doesn’t have to 
> do the same work over and over again.
> It allows to store schema and statistics, which will allow to accelerate 
> queries validation, planning and execution time. Also it increases stability 
> of Drill and allows to avoid different kind if issues: "schema change 
> Exceptions", "limit 0" optimization and so on. 
> One of the main candidates is Hive Metastore.
> Starting from 3.0 version Hive Metastore can be the separate service from 
> Hive server:
> [https://cwiki.apache.org/confluence/display/Hive/AdminManual+Metastore+3.0+Administration]
> Optional enhancement is storing Drill's profiles, UDFs, plugins configs in 
> some kind of metastore as well.
