What
gRPC layer
QueryResponse
contains raw bytes as the payload. We keep interpretation of the payload to our own encoder which this PR introduces. V0 codec is simple and stateless and doesn't deal with the fact every serialized record batch has schema included.As for the encoding, we simply rely on
arrow2
serialization and deserialization constructs for the record batch and we have our own header to differentiate between "no data" and a "record batch" in theQueryResponse
.Example usage:
Depends on
