I think it can avoid that issue. > > Even though a consumer match a queue, message-1 fails to consume and is sent to the delay queue, message-2 may be consumed before message-1. In pull model of orderly consumption, the msg which is failed to consume will not enter the retry queue, it will only be retried locally. Looking at the current impl in the code, the message queue will be locked when clent pops msgs. This can ensure that only one client pulls messages at the same time, but there is no guarantee that only one client is consuming the queue at the same time. Maybe I missed the code, can anyone explain it? -- This is an automated message from the Apache Git Service.
