> I don't see any way to create a new `FixedSizeBinaryArray` with zero length using `try_new`. Is this on-purpose? The comments says 0 should be fine. Is this a bug in arrow-rs? This does seem like a bug; for reference, pyarrow allows it: ```python >>> import pyarrow as pa >>> pa.binary(0) FixedSizeBinaryType(fixed_size_binary[0]) >>> pa.array([], type=pa.binary(0)) <pyarrow.lib.FixedSizeBinaryArray object at 0x102030b80> [] >>> pa.array([], type=pa.binary(0)).type FixedSizeBinaryType(fixed_size_binary[0]) ``` It would be nice to upstream a proper fix to arrow-rs and then can wait for it here; otherwise if we need a fix for DataFusion now we can do a workaround as you describe: > We maybe could create a `FixedSizeBinaryArray` using the `From<ArrayData>` implementation. -- This is an automated message from the Apache Git Service.
