Are you getting any speedup? The benchmark results don't show any difference.

with just save the ChunkLocation entries in the max-heap there's not show speedup, currently I'm still working on the second part of sort individual batches and merge like Table Sort.

@AlvinJ15 @pitrou Benchmark builds are failing because of an issue with aws-sdk-cpp that was fixed in master branch by pinning aws-sdk-cpp version. I recommend getting recent master changes into this branch and rerunning benchmarks.
