[jira] [Created] (PHOENIX-1280) ColumnProjectionFilter makes too many ImmutableBytesPtrs

             Summary: ColumnProjectionFilter makes too many ImmutableBytesPtrs
                 Key: PHOENIX-1280
                 URL: https://issues.apache.org/jira/browse/PHOENIX-1280
             Project: Phoenix
          Issue Type: Bug
            Reporter: Lars Hofhansl


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.
