Lars Hofhansl updated PHOENIX-1280:
-----------------------------------
Attachment: 1280-WIP.txt
W.I.P. patch
* Reuses a single ImmutableBytesWritable for the one time usages
* Removes calls to unnecessary ensureKeyValue
* Saves one lookup into the map - since this is a TreeMap it will save a few
comparisons (at least one).
* hashcode is not used since we're using a TreeMap (so ImmutableBytesWritable
is good here)
Completely untested. Will run some tests, and (presuming not objection) will
commit if I find no issues.
> ColumnProjectionFilter makes too many ImmutableBytesPtrs

> 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.
