Yi Zhang created HIVE-27218:
-------------------------------
Summary: Hive-3 set 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: 3.1.3, 3.1.2, 3.1.0
Reporter: Yi Zhang
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.
