Hi,Yingchun :
Thanks for your reply, I just want to know what's protocol between ReplicaServer and MetaServer. Maybe the simple answer is where the thirft file, Thanks.
From file name,I guess *src/common/metadata.thrift* is one of their.
I'm not the c/c++ code writer, so i can not find it from run source code, remind me if i misse something, Thanks.
Best Regards,
Lan Liang

Hi,
Sorry there are not enough docs about that.
Roughly read about the developing-binary-protocol of Pulsar, it seems
it's designed for communications between producers/consumers and
brokers, which often has a huge amount of data to transport. In
Pegasus, MetaServer is the center management node, it is stateless
that does not contain user data, the ReplicaServer is a data node that
stores a huge amount of data, so communications between MetaServer and
ReplicaServer are very light regularly. So it seems they don't match.
Best regards,
Yingchun Lai

Hi,
Sorry there are not enough docs about that.
Roughly read about the developing-binary-protocol of Pulsar, it seems
it's designed for communications between producers/consumers and
brokers, which often has a huge amount of data to transport. In
Pegasus, MetaServer is the center management node, it is stateless
that does not contain user data, the ReplicaServer is a data node that
stores a huge amount of data, so communications between MetaServer and
ReplicaServer are very light regularly. So it seems they don't match.
