Lars Hofhansl commented on PHOENIX-1280:
----------------------------------------
In 4.0+ we also do not need the call to ensureKeyValue, the cell API is
sufficient.
> ColumnProjectionFilter makes too many ImmutableBytesPtrs

> Project: Phoenix
> Issue Type: Bug
> Reporter: Lars Hofhansl
> Assignee: Anoop Sam John
>
> While tracing through allocated objects during some queries I find that many
> ImmutableBytesPtr objects are created. One offender is ColumnProjectionFilter
> which first creates the columns to be projected and then while scanning make
> a new ImmutableBytesPtr for each single column that passes through the filter.
