Ted Yu commented on HBASE-15480:
--------------------------------
{code}
* Check if the specified keys are contained in the bloom filter.
...
+ public BitSet contains(byte[][] key, int[] keyOffset, int[] keyLength,
ByteBuff bloom) {
{code}
Since multiple keys are checked in the method, shouldn't the parameter names be
in plural ?
BTW I don't find the caller for the new method.
Did I miss something ?

> It is currently inefficient to do lots of bloom filter checks. Each check has
> overhead like going to the block cache to retrieve the block and recording
> metrics. It would be good to have one bloom filter check api that does a
> bunch of checks without so much block retrieval and metrics updates.
