This ensures that transient tables do not block pruning. However, if a transient table is created/deleted again with the same name and never gets a chance to be compacted, then it has a potential to block pruning. One way to handle this would be to keep track of creation time for every table and use that information to remove regions of previous iterations of a transient table. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
