> Hi,
> we've just updated Camel from 4.4 to 4.10 and we've noticed an issue which is likely caused by the changes introduced by CAMEL-21740. We're seeing two issues:
> - When a consumer restarts from the latest event (i.e. all the events have already been consumed) then checking the replay id takes exactly 60s. I think this happens because {{PubSubApiClient}} sets {{FetchRequest.numRequested}} to 1, but there aren't any events to consume; in this scenario the client waits up to 60s before invoking the callback. I'm not sure where this value is configured (client  side? Server side?). I had a look at the Camel code and couldn't find this setting anywhere. I've also tried to pass {{numRequested=0}} and it doesn't work (it returns immediately but it doesn't check the replay id at all)
> - Sometimes the "check initial replay id" call just hangs. Bumping the timeout doesn't seem to help: we're using 5 minutes right now and we're still seeing issues. I'm not sure what's triggering this behavior; AFAICT after we restart the application the call is always successful.
> Based on the comments in CAMEL-21740 I understand that the purpose of this check is to avoid using LATEST if the replay id doesn't exist; I'm wondering if this could be done directly when subscribing to the topic, instead of trying to fetch a single event beforehand.
> Thanks,
> lorenzo
