The documentation does not really make sense when it comes to poll_timeout_ms and fetch_max_wait_ms.
According to the documentation:
- fetch_max_wait_ms has a default value of 500ms
- poll_timeout_ms has a default value of 100ms.
Yet it says that fetch_max_wait_ms should be less than or equal to poll_timeout_ms.
Additionally setting poll_timeout_ms does not seem to do anything. I can't see a difference in the properties of the kafka consumer when changing this value.
Could you provide some explanations please?
