Mike Percy updated KUDU-2645: ----------------------------- Code Review: https://gerrit.cloudera.org/c/12205/ > Diff scanner should perform a merge on the rowset iterators at scan time > ------------------------------------------------------------------------ > > Key: KUDU-2645 > URL: https://issues.apache.org/jira/browse/KUDU-2645 > Project: Kudu > Issue Type: New Feature > Components: tablet > Reporter: Mike Percy > Assignee: Mike Percy > Priority: Major > > In order to perform a diff scan we will need the MergeIterator to ensure that > duplicate ghost rows are not returned in cases where a row was deleted and > flushed, then reinserted into a new rowset during the time period covered by > the diff scan. In such a case, only one representation of the row should be > returned, which is the reinserted one. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
