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?
> Avoid creating List of KeyValue in FilterBase#filterRowCells(List<Cell>)
> ------------------------------------------------------------------------

> Key: HBASE-11147
> URL: https://issues.apache.org/jira/browse/HBASE-11147
> 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.
