ClusterCanalClientTest运行后server端频繁刷日志： [New I/O server worker #1-2] INFO c.a.otter.canal.server.netty.handler.SessionHandler - message receives in session handler

clone的最新的canal项目，用ClusterCanalClientTest能正常获取DB的binlog。但是server端疯狂刷日志。虽然是INFO，但是感觉不是很正常。我logback那边开启了这个appender

开启了这个STDOUT的appender

INFO日志？只是打印了一下日志

哦哦，知道了。netty里面的长连接，server端一直长轮询在拉消息，所以sessionHandler被频繁调用了~
