Subject [jira] [Updated] (HIVE-23573) [HMS] Advance the write id for the table for both DDL
Date Thu, 11 Jun 2020 07:20:00 GMT

     [ https://issues.apache.org/jira/browse/HIVE-23573?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Kishen Das updated HIVE-23573:
------------------------------
    Description: Every write request will advance the write id for the table for DDL. The
writeid will be marked committed locally in HMS client. The next read request is guaranteed
to read from db until the notification log catch up to the commit message of the transaction
commit, since the writeid is newer than the cache (the writeid for the transaction is committed
locally, but is not committed on HMS until notification log catch up).  (was: Every write
request will advance the write id for the table for both DML/DDL. The writeid will be marked
committed locally in HMS client. The next read request is guaranteed to read from db until
the notification log catch up to the commit message of the transaction commit, since the writeid
is newer than the cache (the writeid for the transaction is committed locally, but is not
committed on HMS until notification log catch up).)
