Chia-Ping Tsai commented on HBASE-15410:
----------------------------------------
{code}
case SEEK_NEXT_USING_HINT:
- seekHintFilter = filter;
- return code;
+ seekHintFilter.add(filter);
+ continue;
default:
- return code;
+ if (seekHintFilter.isEmpty()) {
+ return code;
+ }
{code}
Should we clear the seekHintFilter before checking cell? Otherwise, we may give
the previous hint cell to current cell.
> Utilize the max seek value when all Filters in MUST_PASS_ALL FilterList
> return SEEK_NEXT_USING_HINT

> 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.
