[ https://issues.apache.org/jira/browse/HIVE-16092?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel=15895447#comment-15895447 ] Sergey Shelukhin commented on HIVE-16092: - I mean, eventually we won't be able to get out of having the global txnid, right? So might as well do it now. Do you have some existing code in particular that would break when that is done, or some specific future scenario? > Generate and use universal mmId instead of per db/table > --- > > Key: HIVE-16092 > URL: https://issues.apache.org/jira/browse/HIVE-16092 > Project: Hive > Issue Type: Sub-task >Reporter: Wei Zheng >Assignee: Wei Zheng > > To facilitate later replacement for it with txnId -- This message was sent by Atlassian JIRA (v6.3.15#6346)
