Although Arrow results are split into batches with a size limit according to estimation, the
size of the batches is not guaranteed to be less than the limit, especially when a single row
is larger than the limit, in which case the server will fail to split it further into smaller
batches. As a result, the client may encounter a gRPC error stating “Received message larger
than max” when a batch is too large.
If allow_arrow_batch_chunking=true, the server will split large Arrow batches into smaller chunks,
and the client is expected to handle the chunked Arrow batches.

If false, the server will not chunk large Arrow batches.

bool allow_arrow_batch_chunking = 1;

Optional preferred Arrow batch size in bytes for the server to use when sending Arrow results.
The server will attempt to use this size if it is set and within the valid range
([1KB, max batch size on server]). Otherwise, the server's maximum batch size is used.
