Review request for hive, Alexander Kolbasov, Ashutosh Chauhan, and Eugene
Koifman.
Bugs: HIVE-20459
https://issues.apache.org/jira/browse/HIVE-20459
Repository: hive-git
Description
-------
we currently have ThriftHiveMetastore.get_open_txns() which maps to
TxnHandler.getOpenTxns(). The usual usage is
TxnUtils.createValidReadTxnList(GetOpenTxnsResponse txns, long currentTxn)
where the complete list transactions is obtained from Metastore and then
anything above currentTxn is thrown away.
Would be useful to add ThriftHiveMetastore.get_open_txns(long txnid) and
TxnHandler.getOpenTxns(long) to not retrieve things that will be thrown away.
Especially when there are a lot of running transactions.
