> We found that if the cluster was written only by streaming, it was stable. If async write and Streaming Write are mixed, the streaming will become unstable.  We found  that some pipline leaders would often change during mixed writes.  
> It seems that leader switch has a great influence on the stability of streaming. Although the RoutingTable is initialized only once when the Ozone client is setup. In the actual pipline, the order of the nodes has changed.  So I wonder if in ratis, whether the stream transmission is processed when change leader.
