我正在使用默认设置运行 click house 版本“20.6.4”。在浏览日志时，我发现这些日志非常丰富。
ServerErrorHandler: Code: 210, e.displayText() = DB::NetException: Connection reset by peer, while reading from socket
和
u003cWarning\u003e ConnectionPoolWithFailover: Connection failed at try №1, reason: Code: 209, e.displayText() = DB::NetException: Timeout: connect timed out: 172.16.*.*:9000 (172.16.*.*:9000) (version 20.6.3.28 (official build))","msg_id":"SERVER-1","namespace":"clickhouse.server","priority":6,"timestamp":"2020-09-21T00:01:23.623067Z","user_id":"","user_name":""}
我使用默认设置的 go-clickhouse 客户端(没有更改任何超时) 几乎每分钟插入数据(大约60-70k行) 尽管似乎没有任何影响，但得到了很多这些 这些是我的超时相关设置:

Is there anything i can change to minimize these errrors??
最佳答案
Connection reset by peer, while reading from socket
该消息中的 IP 地址是什么？是CH服务器还是客户端？ 但这确实是一个错误。这只是意味着客户端已经离开，服务器没有收到所有预期的数据。
关于clickhouse - 出现大量 "DB::NetException: Connection reset by peer, while reading from socket"错误，这些错误会产生大量噪音，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/64064438/
