---------------------------------
Summary: Add scanner stat for number of deleted rows skipped
Key: KUDU-2400
URL: https://issues.apache.org/jira/browse/KUDU-2400
Project: Kudu
Issue Type: Improvement
Components: supportability, tablet
Reporter: Todd Lipcon
I'm doing some testing where I deleted all the rows in a very large table and
then reinserted a bunch of new data. My scans are now relatively slow because
they are skipping over all of these deleted rows, but at first glance it wasn't
really clear what was going on. If on the /scans dashboard we surfaced info
indicating that it scanned over 1M deleted rows to return 1000 live ones it
would help understand the performance.
