Michael-J-Ward opened a new pull request, #6320:
URL: https://github.com/apache/arrow-rs/pull/6320
Ref:
# Which issue does this PR close?
Closes #6318.
# Rationale for this change
`arrow-rs` already has the capability of handling RecordBatches with no
columns or data but non-zero row counts
https://github.com/apache/arrow-rs/pull/1552.
However, `from_pyarrow_bound` for `RecordBatch` does not currently take
advantage of it, which causes an error when running `select count(*)` from
pyarrow datasets in `datafusion-python`
https://github.com/apache/datafusion-python/issues/800.
# What changes are included in this PR?
This updates the `impl FromPyarrowBound` for `RecordBatch` to use
`try_new_with_options` instead of the default `try_new`.
# Are there any user-facing changes?
Yes, `from_pyarrow_bound` will now succeed for a RecordBatch with no columns
but a row-count set.
