Serialization/deserialization is rarely the bottleneck, so don't prematurely optimise for it. The candidates for fast serialization/deserialization that have implementations for all major programming languages are: * Plain JSON using the simdjson library, optionally in NDJSON format (line separated), optionally compressed with LZ4. * CBOR (like msgpack but with more datatypes/features) * msgpack * Protocol Buffers (optionally with gRPC)
