Sergey Shelukhin reassigned HIVE-20047: --------------------------------------- Assignee: Sergey Shelukhin > [phase 1.5] consider removing txnID argument for txn stats methods > ------------------------------------------------------------------ > > Key: HIVE-20047 > URL: https://issues.apache.org/jira/browse/HIVE-20047 > Project: Hive > Issue Type: Sub-task > Reporter: Sergey Shelukhin > Assignee: Sergey Shelukhin > Priority: Major > Attachments: HIVE-20047.patch > > > Followup from HIVE-19975. > W.r.t. write IDs and txn IDs, stats validity check currently verifies one of > two things - that stats write ID is valid for query write ID list, or that > stats txn ID (derived from write ID) is the same as the query txn ID. > I'm not sure the latter check is needed; removing it would allow us to make a > bunch of APIs a little bit simpler. > [~ekoifman] do you have any feedback? Can any stats reader (e.g. compile) > observe stats written by the same txn; but in such manner that it doesn't > have the write ID of the same-txn stats writer, in its valid write ID list? > I'm assuming it's not possible, e.g. in multi statement txn each query would > have the previous same-txn writer for the same table in its valid write ID > list? -- This message was sent by Atlassian JIRA (v7.6.3#76005)
