Zheng Hu updated HBASE-18410:
-----------------------------
Release Note:
In this task, we fixed all existing bugs in FilterList, and did the code
refactor which ensured interface compatibility . The primary bug fix are :
FilterList with MUST_PASS_ONE
we divided the FilterList into two separated sub-classes: FilterListWithOR and
FilterListWithAND, The FilterListWithOR has been optimised to choose the next
minimal step to seek cell rather than SKIP cell one by one, and the
FilterListWithAND has been optimised to choose the next maximal key to seek
among sub-filters in filter list. All in all, The code in FilterList is clean
and easier to follow now.
Note that ReturnCode NEXT_ROW has been redefined as skipping to next row in
current family, not to next row in all family. it’s more reasonable, because
ReturnCode is a concept in store level, not in region level.
