Kafka REST Proxy sometimes read nothing from an non-empty topics on the first run

[Yiwei Chen]

Hello,

I am using Confluence Platform 2.0.1 to provide a Rest API Consumer solution for my Kafka Cluster.

The API works well on creating and deleting consumer. However, sometimes it returns "[ ]" when I consume the the topics the first time after creating the consumer. I need to request the same API again to get the desire message.

Does anyone know how to fix it? Thank you so much!

Not every request is guaranteed to return data. In fact, this would be normal if you had a topic that infrequently received data. The empty list just indicates no data was fetched in the period that request was waiting at the proxy for data.
