(was: Hive-3 set hive.materializedview.rewriting default to false)
> Hive-3 switch hive.materializedview.rewriting default to false
> --------------------------------------------------------------
>
> Key: HIVE-27218
> URL: https://issues.apache.org/jira/browse/HIVE-27218
> Project: Hive
> Issue Type: Improvement
> Components: Hive
> Affects Versions: 3.1.0, 3.1.2, 3.1.3
> Reporter: Yi Zhang
> Priority: Major
>
> https://issues.apache.org/jira/browse/HIVE-19973 switched
> hive.materializedview.rewriting default from false to true, however user
> observed high latency at query compilation as they have large amount of
> databases (5k), each call to a remote metastore DB adds up the latency to
> minutes, each query compilation time is high.
> as hive-4 have improvements in HIVE-21631 and HIVE-21344 backport is
> unlikely, suggest to turn this false by default in hive-3.
