--------------------------------------
Summary: Use arena allocation to improve protobuf message passing
performance.
Key: MESOS-6971
URL: https://issues.apache.org/jira/browse/MESOS-6971
Project: Mesos
Issue Type: Improvement
Components: libprocess, technical debt
Reporter: Benjamin Mahler
The protobuf message passing provided by {{ProtobufProcess}} provide const
access of the message and/or its fields to the handler function.
This means that we can leverage the [arena
allocator|https://developers.google.com/protocol-buffers/docs/reference/arenas]
provided by protobuf to reduce the memory allocation cost during
de-serialization and improve cache efficiency.
This would require using protobuf 3.x with "proto2" syntax (which appears to be
the default if unspecified) to maintain our existing "proto2" requirements. The
upgrade to protobuf 3.x while keeping "proto2" syntax should be tackled via a
separate ticket that blocks this one.
