Andreas Neumann reassigned TEPHRA-244: -------------------------------------- Assignee: Poorna Chandra (was: Andreas Neumann) > Invalid tx pruning does not handle deletion of tables well > ---------------------------------------------------------- > > Key: TEPHRA-244 > URL: https://issues.apache.org/jira/browse/TEPHRA-244 > Project: Tephra > Issue Type: Bug > Components: core, manager > Affects Versions: 0.12.0-incubating > Reporter: Andreas Neumann > Assignee: Poorna Chandra > Fix For: 0.13.0-incubating > > > Suppose an application regularly creates and deletes tables (for example, > temporary tables). In such a scenario, there will always be such a temporary > table when pruning runs, and its regions will be recorded for that time. > However, the region will be deleted before it ever compacts or flushes, and > it will never record prune information. Because all prune times have such > regions, there will never be a set of transactional regions that all have > prune info, and pruning will never happen. > The fix is to exclude deleted tables from the list of regions at each time. > This is all regions of deleted tables (tables that do not exist any more), > not deleted regions: a region may disappear due to a split and its data will > be in new regions. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
