Paul Yang updated HIVE-1768: ---------------------------- Attachment: HIVE-1768.1.patch > Update transident_lastDdlTime only if not specified > --------------------------------------------------- > > Key: HIVE-1768 > URL: https://issues.apache.org/jira/browse/HIVE-1768 > Project: Hive > Issue Type: Improvement > Components: Metastore > Affects Versions: 0.7.0 > Reporter: Paul Yang > Assignee: Paul Yang > Attachments: HIVE-1768.1.patch > > > Currently, whenever a table/partition is created/altered, the field > 'transient_lastDdl' time is updated with the current timestamp. For normal > operations, this is the desired behavior. However for some housekeeping > tasks, it may be helpful if the user could keep the existing value (or set it > to something different). > One example where this is useful is if a partition is copied between > clusters. If the last modified time were kept same after the initial copy, it > would be easy to know if one partition were overwritten/updated by comparing > timestamps. > This patch alters the behavior of create/alter methods in the metastore API > to update the timestamp only if it is not specified in the object. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
