-------------------------------------------
Summary: Improve supportability of the automatic invalidate feature
Key: IMPALA-7975
URL: https://issues.apache.org/jira/browse/IMPALA-7975
Project: IMPALA
Issue Type: Sub-task
Reporter: Vihang Karajgaonkar
Assignee: Vihang Karajgaonkar
Some of the things which can be done to improve supportability of this feature:
* Add metrics to detect issues pertaining to this feature
# Time taken to fetch the notifications (Would be useful to have average, min,
max)
# Time taken to process a batch of events received
# Number of times particular table was invalidated (would be useful to have
some rate metric like number_of_invalidates/per_hour)
* Ability to turn ON/OFF for this feature (possibly without the need of a
restart)
