> 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.
