> jumping back to this topic:
Completely agree with your argument. Makes sense to me. I'll ignore the event 
instead of invalidating the metadata object.

Should we throw a LOG.warn() saying the next access to this metadata object 
might be stale so issue IM/RT to fetch the latest snapshot or should I leave it 
as it is since a lot of events on the disabled table might flood the log with 
trivial warning?

We can ignore the event if the table is incomplete. But I'm planning to remove 
this part based on your other comment.
