kangkaisen commented on issue #3330: Fix rowset_meta race condition for commit_txn in TxnManager URL: https://github.com/apache/incubator-doris/pull/3330#issuecomment-615059049 > I think TxnManager is better to not know the RowsetMeta concept. > It's only to know the Transaction concept, so I think the previous name is OK. 1. TxnManager **has known** the RowsetMeta concept. 2. `_txn_mutex` normally means we should get this lock for most of txn operations, but we only get it when `commit_txn` and `publish_txn` 3. We really use `_txn_mutex` to protect the rowset meta.
