I reread the format guide again, and I think the Arrow file format is an extension of the IPC (stream) format https://arrow.apache.org/docs/format/Columnar.html#ipc-file-format It looks like the file format simply has a few extra header bytes and then a footer. Otherwise it is the same as the stream. format So we should be able to support both formats fairly straightforwardly It may be possible to simply use the [StreamReader](https://docs.rs/arrow-ipc/55.2.0/arrow_ipc/reader/struct.StreamReader.html) rather than the [`FileReader`](https://docs.rs/arrow-ipc/55.2.0/arrow_ipc/reader/struct.FileReader.html) in the underlying code for `ArrowFormatFactory` https://github.com/apache/datafusion/blob/2741c60ad9d637e5014d201802abb25562449491/datafusion/core/src/datasource/file_format/arrow.rs#L110-L109 -- This is an automated message from the Apache Git Service.
