Mikhail Antonov commented on HBASE-11147:
-----------------------------------------

Unless I'm missing something, you can't do (ignored instanceof List<KeyValue>), because of type erasure in generic?

>             Project: HBase
>          Issue Type: Task
>            Reporter: Ted Yu
>            Priority: Minor
>
> Currently a List of KeyValue's is always created:
> {code}
>     List<KeyValue> kvs = new ArrayList<KeyValue>(ignored.size());
> {code}
> When passed ignored List is of KeyValue (which is the only implementation of Cell at the moment), the above step should be avoided.
> This would reduce creation of short-lived objects.
