Eugene Koifman commented on HIVE-17457:
---------------------------------------
If the file is readable it's simpler than this:
all rows in base_x that is the result of insert/load data with OVERWRITE are
created by the aborted transaction x and so will be skipped by Acid readers.
It would be more performant to filter out base_x at file level.
\\
What if there is base_5 and delta_6_6 where txnid:6 is aborted - does
compaction produce base_6? Probably not since getAcidState() should skip
delta_6. Need to verify.

> HIVE-14988 adds support for Insert Overwrite for Acid tables.
> once we have direct write to target dir (i.e. no move op) - how do we handle
> the case where the txn running IOW aborts? See if getAcidState() does the
> right thing
