2.replication_buffer的被首次使用 当且仅当slave与master首次或者出于某种原因,需要全量rdb传输数据后,然后会把replication_buffer中的数据,再次全量传给slave。 注:此阶段称作主从复制的第一阶段,全量rdb+ replication_buffer。 第二阶段(命令传播),主要是增量传输,此时replication_backlog_buffer出场。 2.replication_b...
2、replication buffer:Redis和客户端通信也好,和从库通信也好,Redis都需要给分配一个 内存buffer进行数据交互,客户端是一个client,从库也是一个client,我们每个client连上Redis后,Redis都会分配一个client buffer,所有数据交互都是通过这个buffer进行的:Redis先把数据写到这个buffer中,然后再把buffer中的数据发到client s...

During the process of propagating to a replica, if the replica is disconnected(marked as CLIENT_CLOSE_ASAP) due to exceeding the output buffer limit, we should remove its reference to the global replication buffer to avoid the global replication buffer being unable to be properly trimmed due to...

Using virtual output queues in ingress buffers may reduce risk of egress port congestion, as egress buffers have more limited resources than ingress buffers; however, relying solely on ingress replication for multicast traffic may hinder unicast traffic. Ingress buffer replication of multicast traffic ...
