---------------------------------------
FYI, [~ikryvenko]
> extend OpenTxnRequest with transaction type
> -------------------------------------------
>
> Key: HIVE-21036
> URL: https://issues.apache.org/jira/browse/HIVE-21036
> Project: Hive
> Issue Type: Bug
> Components: Transactions
> Affects Versions: 4.0.0
> Reporter: Eugene Koifman
> Priority: Major
>
> There is a {{TXN_TYPE}} field in {{TXNS}} table.
> There is {{TxnHandler.TxnType}} with legal values. It would be useful to
> TxnType a {{Thrift}}, add a new {{COMPACTION}} type object and allow setting
> it in {{OpenTxnRequest}}.
> Since HIVE-20823 compactor starts a txn and should set this.
> Down the road we may want to set READ_ONLY either based on parsing of the
> query or user input which can make {{TxnHandler.commitTxn}} faster.
