--------------------------------------
Summary: Drill Metadata management "Drill MetaStore"
Key: DRILL-6552
URL: https://issues.apache.org/jira/browse/DRILL-6552
Project: Apache Drill
Issue Type: New Feature
Components: Metadata
Affects Versions: 1.13.0
Reporter: Vitalii Diravka
Assignee: Vitalii Diravka
Fix For: 2.0.0
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:

Optional enhancement is storing Drill's profiles, UDFs, plugins configs in some
kind of metastore as well.
