接口 MessageStreamApi

所有已知实现类:

MessageStreamImpl

public interface MessageStreamApi

Stream (large) Message(s) asynchronously to the leader. Once a stream has been closed or has been signaled an end-of-request, the leader creates a raft log entry for the request and then replicates the log entry to all the followers. Note that this API is similar to AsyncApi.send(Message) except that MessageStreamApi divides a (large) message into multiple (small) sub-messages in the stream but AsyncApi.send(Message) sends the entire message in a single RPC. For sending large messages, MessageStreamApi is more efficient than AsyncApi.send(Message)}. Note also that this API is different from DataStreamApi in the sense that this API streams messages only to the leader but DataStreamApi streams data to all the servers in the RaftGroup.
