Mike Percy created KUDU-2645: -------------------------------- Summary: 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
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)
