Istvan Toth commented on HBASE-28621:
-------------------------------------
Thanks for looking into this [~chandrasekhar.k].
I can see that you have assigned several tickets to yourself in the last few
days.
Can you please de-assign the ones that you are not actively working on at the
moment ?
Other ppl are also interested in fixing some of them, so it's important not to
"lock" them unless you are actively working on them.
> PrefixFilter should use SEEK_NEXT_USING_HINT
> ---------------------------------------------

> Key: HBASE-28621
> URL: https://issues.apache.org/jira/browse/HBASE-28621
> Project: HBase
> Issue Type: Improvement
> Components: Filters
> Reporter: Istvan Toth
> Assignee: Chandra Sekhar K
> Priority: Major
> Labels: beginner, beginner-friendly
>
> Looking at PrefixFilter, I have noticed that it doesn't use the
> SEEK_NEXT_USING_HINT mechanism.
> AFAICT, we could safely set the the prefix as a next row hint, which could be
> a huge performance win.
> Of course, ideally the user would set the scan startRow to the prefix, which
> avoids the problem, but the user may forget to do that, or may use the filter
> in a filterList that doesn't allow for setting the start/stop rows close tho
> the prefix.
