Review request for hive, Laszlo Pinter and Peter Vary.
Bugs: HIVE-23280
https://issues.apache.org/jira/browse/HIVE-23280
Repository: hive-git
Description
-------
When a txn is aborted and the compaction threshold for number of aborted txns
is not reached then the aborted transaction can remain forever in the RDBMS
database. This could result in several serious performance degradations:
getOpenTxns has to list this aborted txn forever
TXN_TO_WRITE_ID table is not cleaned
We should add a threshold, so after a given time the compaction is started
anyway.
