Wei Zheng commented on HIVE-16063:
----------------------------------
We will open transaction for all mm table write operations. Once we open a
transaction in Driver, the txnId should be available across the session.
> instead of explicitly specifying mmWriteId during compilation phase, it
> should only be generated whenever needed during runtime

> For ACID transaction logic to work with mm table, first thing is to make the
> ID usage logic consistent. ACID stores valid txn list in VALID_TXNS_KEY.
