-----------------------------------
Summary: 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: Istvan Toth
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, if the user doesn't, then we effectively do a full scan
until the prefix is reached.
