The CI fails because PartialSort will replace Sort in some test cases like
below, I can change that if others in this PR looks good.
```
expected:
[
"SortPreservingMergeExec: [a@0 ASC,b@1 ASC]",
" SortExec: expr=[a@0 ASC,b@1 ASC,c@2 ASC]",
" RepartitionExec: partitioning=RoundRobinBatch(10),
input_partitions=1",
" CsvExec: file_groups={1 group: [[x]]}, projection=[a, b, c, d,
e], output_ordering=[a@0 ASC, b@1 ASC], has_header=false",
]
actual:
[
"SortPreservingMergeExec: [a@0 ASC,b@1 ASC]",
" PartialSortExec: expr=[a@0 ASC,b@1 ASC,c@2 ASC],
common_prefix_length=[2]",
" RepartitionExec: partitioning=RoundRobinBatch(10),
input_partitions=1",
" CsvExec: file_groups={1 group: [[x]]}, projection=[a, b, c, d,
e], output_ordering=[a@0 ASC, b@1 ASC], has_header=false",
]
```
