Lars Hofhansl commented on HBASE-9769:
--------------------------------------
Another idea I had was to make use of the column family's VERSIONS setting. If
it is "small" use INCLUDE and SKIP in the ExplicitColumnTracker, otherwise use
INCLUDE_AND_SEEK_NEXT_COL and SEEK_NEXT_COL. In my tests this yields a nice
improvement bringing ExplicitColumnTracker on par with
ScanWildcardColumnTracker. For now I defined "small" as 10, but that needs to
be tested more.
