> Currently, we do not support FULL OUTER JOIN in MapJoin.
> Rough TPC-DS timings run on laptop:
> (NOTE: Query 51 has PTF as a bigger serial portion -- Amdahl's law at play)
> FULL OUTER MapJoin OFF = MergeJoin
> Query 51:
> o Vectorization OFF
> • FULL OUTER MapJoin OFF: 4:30 minutes
> • FULL OUTER MapJoin ON: 4:37 minutes
> o Vectorization ON
> • FULL OUTER MapJoin OFF: 2:35 minutes
> • FULL OUTER MapJoin ON: 1:47 minutes
> Query 97:
> o Vectorization OFF
> • FULL OUTER MapJoin OFF: 2:37 minutes
> • FULL OUTER MapJoin ON: 2:42 minutes
> o Vectorization ON
> • FULL OUTER MapJoin OFF: 1:17 minutes
> • FULL OUTER MapJoin ON: 0:06 minutes
> FULL OUTER Join 10,000,000 rows against 323,910 small table keys
> o Vectorization ON
> • FULL OUTER MapJoin OFF: 14:56 minutes
> • FULL OUTER MapJoin ON: 1:45 minutes
> FULL OUTER Join 10,000,000 rows against 1,000 small table keys
> o Vectorization ON
> • FULL OUTER MapJoin OFF: 12:37 minutes
> • FULL OUTER MapJoin ON: 1:38 minutes
> Hopefully, someone will do large scale cluster testing.
> [DynamicPartitionedHashJoin] MapJoin should scale dramatically better than
> [Sort] MergeJoin reduce-shuffle.
