Review Comment:
Small suggestion to improve clarity. This makes it more verbose, but I think
it's worthwhile:
```suggestion
There are three different options for compression of record batch
body buffers: Buffers can be uncompressed, buffers can be
compressed with the``lz4`` compression codec, or buffers can
be compressed with the ``zstd`` compression codec. Buffers in
the flat sequence of a message body must be either all
uncompressed or all compressed separately using the same codec.
```
