Eugene Koifman commented on HIVE-19124:
---------------------------------------
Hold on. We already have a mechanism for compactor to make sure it doesn't
compact above an open txn:
TxnUtils.createValidCompactWriteIdList() .
This reinvents the wheel and add a new one to do the same thing in the Reader
list. Why is this good?
> implement a basic major compactor for MM tables
