[jira] [Commented] (HBASE-12303) Seek to next row after family delete markers
[ https://issues.apache.org/jira/browse/HBASE-12303?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanelfocusedCommentId=14178765#comment-14178765 ] Lars Hofhansl commented on HBASE-12303: --- Opened HBASE-12311 for more brainstorming around this. Seek to next row after family delete markers Key: HBASE-12303 URL: https://issues.apache.org/jira/browse/HBASE-12303 Project: HBase Issue Type: Bug Reporter: Lars Hofhansl Attachments: 12303.txt Currently we seek to the next column when we encounter a family delete marker. I think we safely seek the current store to next row. We ran into a scenario with very slow scans after a lot of rows have been deleted with family delete markers. Some profiling revealed that we seek for once for each row and column. This won't make this go away entirely, but at least we can seek once per row rather than once per column. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
