Andrew Sherman commented on HIVE-18193: --------------------------------------- Hi [~anishek] can you explain a little more about this. How is the write id generated? Will this require on-disk data to be rewritten? Sorry if I missed previous discussions but is there a design for snapshot isolation. Thanks > Migrate existing ACID tables to use write id per table rather than global > transaction id > ---------------------------------------------------------------------------------------- > > Key: HIVE-18193 > URL: https://issues.apache.org/jira/browse/HIVE-18193 > Project: Hive > Issue Type: Bug > Components: HiveServer2, Transactions > Affects Versions: 3.0.0 > Reporter: anishek > Assignee: anishek > Fix For: 3.0.0 > > > dependent upon HIVE-18192 > For existing ACID Tables we need to update the table level write id > metatables/sequences so any new operations on these tables works seamlessly > without any conflicting data in existing base/delta files. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
