# replace externalizable with serializable
# see if custom serialization is needed for metrics, etc
# serVerUid = 0

> Please see if we can address the following
> # Avoid extra-serializations. We should not read, deserialize and serialize message again. Instead we should read, deserialize, process and if message stays unchanged, send previously read bytes to next node
> # Can we make the protocol extensible? Reserve flags, binary fields, e.g.
> # Need somehow optimize heartbeats processing. This message usually is changed during processing.
