Arnab Karmakar commented on IMPALA-13449:
-----------------------------------------

Thanks for the heap-dump guidance. However, IMPALA-13794 appears to cover 
Iceberg table memory estimation.
This ticket originally also mentioned external non-Iceberg tables, which don't 
seem to be in IMPALA-13794's scope.

Can you confirm:

1. Does IMPALA-13794 fully duplicate this ticket (in which case we 
close/re-scope)?

2. Or can this ticket still cover external non-Iceberg {{HdfsTable}} estimate 
improvements?

If external tables remain in scope, what are those gaps we should be looking 
at? For example, estimates for tables stored in external object stores dont 
account numBlocks.
