Quanlong Huang commented on IMPALA-14230:
-----------------------------------------
[~arnabk1108] Thanks for volunteering for this. The code change won't be
complex but this task requires thorough testing and some downstream work. Might
be better to be assigned to other folks.
> Add a "catch-up" mode to EventProcessor
> ---------------------------------------
>
> Key: IMPALA-14230
> URL: https://issues.apache.org/jira/browse/IMPALA-14230
> Project: IMPALA
> Issue Type: New Feature
> Components: Catalog
> Reporter: Quanlong Huang
> Assignee: Yida Wu
> Priority: Critical
>
> When HMS events processing has a large lag, we need EventProcessor to quickly
> catch up with HMS by simply processing the events as invalidations, i.e.
> falling back to the behavior before IMPALA-9101 that table level events just
> invalidate the table.
> This will also be useful in catalogd HA failover that the passive catalogd
> wants to quickly catch up with HMS.
