[FLINK-23712] Improve Protobuf serialization performance Profiling allocations shows that around 25% of the allocations happens while parsing Protobuf, this happens because the CodedInputStream/CodedOutputStream allocate a 4kb buffer on construction. This can be easily avoided by caching and reusing them. This closes #251.
