> The ACID shuffle disabled murmur hash for the shuffle, due to the bucketing
> requirements demanding the writable hashcode for the shuffles.
> {code}
> boolean useUniformHash = desc.getReducerTraits().contains(UNIFORM);
> if (!useUniformHash) {
> return false;
> }
> {code}
> This check protects the fast ReduceSink ops from being used in ACID inserts.
> A specialized case for the following pattern will make ACID insert much
> faster.
> {code}
> Reduce Output Operator
> sort order:
> Map-reduce partition columns: _col0 (type: bigint)
> value expressions: ....
