> 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.
