Subject Re: Kafka - Possible messages order

What exactly is the problem?

Kafka states it in documentation and it is not new.

Quote from docs: max.in.flight.requests.per.connection – The maximum number of unacknowledged
requests the client will send on a single connection before blocking. Note that if this setting
is set to be greater than 1 and there are failed sends, there is a risk of message re-ordering
due to retries (i.e., if retries are enabled).

The possible problem is only with some people not able to read documentation.

Hi there,

Recently we found this blog entry about a possible problem with messages order: https://blog.softwaremill.com/does-kafka-really-guarantee-the-order-of-messages-3ca849fd19d2<https://eur02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fblog.softwaremill.com%2Fdoes-kafka-really-guarantee-the-order-of-messages-3ca849fd19d2&data=02%7C01%7Caksoldatov%40avito.ru%7C6ef8bd10a67b4bef52fb08d72c8ad121%7Caf0e07b3b90b472392e63fab11dd5396%7C1%7C0%7C637026847034629468&sdata=%2BulzkEeXQ6xhczBYfYQ8wnvWrpW%2Fs3wVtQaGGwIgPbM%3D&reserved=0>

Please could you confirm about? And if so, how to fix? Blog entry suggesting how to.
