I've these errors in replace in replace_with_order_preserving_variants tests:

expected:
[
"SortExec: expr=[a@0 ASC NULLS LAST], preserve_partitioning=[false]",
" CoalescePartitionsExec",
" RepartitionExec: partitioning=Hash([c@1], 8), input_partitions=8",
" RepartitionExec: partitioning=RoundRobinBatch(8), input_partitions=1",
" StreamingTableExec: partition_sizes=1, projection=[a, c, d], infinite_source=true, output_ordering=[a@0 ASC NULLS LAST]",
]
actual:
[
"SortExec: expr=[a@0 ASC NULLS LAST], preserve_partitioning=[false]",
" CoalescePartitionsExec",
" RepartitionExec: partitioning=Hash([c@2], 8), input_partitions=8",
" RepartitionExec: partitioning=RoundRobinBatch(8), input_partitions=1",
" StreamingTableExec: partition_sizes=1, projection=[a, b, c, d], infinite_source=true, output_ordering=[a@0 ASC NULLS LAST]",
]

Not sure why but projection changes so I'm working on fixing it

There are two function having the same name (stream_exec_ordered), one in replace_with_order_preserving_variants.rs with a built-in projection, and one in core/src/test/mod.rs, w/o a projection, which differs the test results. You've mixed up them. I guess you've deleted one of them actually.

Thank you @buraksenn and @berkaysynnada

I did some spot checks on this PR and I think it looks EPIC -- very nice. The fact that no plans change gives me confidence the refactoring is good.

I took the liberty of pushing a commit that removed a chance to the datafusion-testing pin:

But otherwise I think this is ready to merge. I will leave it open a bit longer to give @berkaysynnada a chance to comment if they want.

I did some random checks, lgtm

LGTM, thank you @buraksenn. I'll continue with the #14190
