Description

RocketMQ Brokers periodically register itself against namesrv to maintain its liveness.
In case a broker has many topics, a 10 thousand or more, two major problematic issues show up:
1) Current serialization of RegisterBrokerBody would create a large String object, which stresses GC a lot, especially when G1 is used.
2) Transmission this bulk of data takes up significant portion of bandwidth.
