Ted Yu commented on HBASE-15410:
--------------------------------
It seems the following two fields of FilterListBase:
{code}
protected final Set<Filter> filters;
/**
* For each sub-filter in filter list, we save a boolean flag to indicate
that whether the return
* code of filterCell(c) for sub-filter is INCLUDE* (INCLUDE,
INCLUDE_AND_NEXT_COL,
* INCLUDE_AND_SEEK_NEXT_ROW) case. if true, we need to transform cell for
the sub-filter.
*/
protected ArrayList<Boolean> subFiltersIncludedCell;
{code}
can be combined into one field with type: Map<Filter, Boolean>
> Utilize the max seek value when all Filters in MUST_PASS_ALL FilterList
> return SEEK_NEXT_USING_HINT

> As Preston mentioned in the comment in HBASE-15243:
> https://issues.apache.org/jira/browse/HBASE-15243?focusedCommentId=15143557&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-15143557
> An optimization for filters returning a SEEK_NEXT_USING_HINT would be to seek
> to the highest hint (Any previous/lower row won't be accepted by the filter
> returning that seek).
> This JIRA is to explore this potential optimization.
