> Key: IMPALA-14131
> URL: https://issues.apache.org/jira/browse/IMPALA-14131
> Project: IMPALA
> Issue Type: New Feature
> Components: Catalog
> Reporter: Quanlong Huang
> Assignee: Sai Hemanth Gantasala
> Priority: Major
>
> Users might want to roll out EventProcessor job by job and turn it off on all
> db/tables by default. It's tedious to set "impala.disableHmsSync" to "true"
> on all dbs. If a db has some tables that want to turn event processing on,
> users should set "impala.disableHmsSync" to "true" on all other tables in
> that db, which is also tedious.
> We need a catalogd startup flag like disable_hms_sync_by_default which is the
> default value of "impala.disableHmsSync" when it's missing in db/table
> properties. It's independent to hms_event_polling_interval_s that catalogds
> will still poll HMS events based on hms_event_polling_interval_s, but if
> disable_hms_sync_by_default is true, events on all db/tables will be skipped
> unless the db/table has property "impala.disableHmsSync"="false".
