Arina Ielchiieva updated DRILL-6552: ------------------------------------ Fix Version/s: (was: 1.17.0) 1.18.0 > 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: Vova Vysotskyi > Priority: Major > Labels: doc-impacting > Fix For: 1.18.0 > > > 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: > [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. -- This message was sent by Atlassian Jira (v8.3.4#803005)
