Conversation
Thanks. For context and future reference, here's some numbers from a test I ran on Friday: #414 (comment) |

@orpiske can you please rebase so your branch will pick up the newly poiting to master gh actions? Thanks |
Sure thing. |
This adds a reference implementation for checking the resource usage of the RabbitMQ component while iddle. The motivation for this is related to the github issue apache#414.

I think it should be ok now, @oscerd |

Thanks, I think @valdar is reviewing. |

Hi @orpiske great work! I was wondering which one of the contributions is predominant: better handling the remaining time or returning Do you mind, since you already have the performance tests at hand, doing a quick comparison towards just returning |

Thanks! And thanks for the review!
The biggest gain is related to avoiding the busy spin. On the previous code we were returning immediately from the receiveNoWait and so the loop was running thousands of times per poll. The change replaces the busy spin with a direct call to the receive, blocking for at most
I tried with returning the null as well. I have a flame graph with that test with null available here. It doesn't seem to affect the performance, but I changed it nonetheless because that way it complies with the connect API. |
This modifies the code so that it blocks while waiting for the messages to arrive while also respecting the maxPollDuration.

@orpiske thanks for the insight on this, I thought it was something similar but I just wanted to be sure. |
|
I believe after merging this we could cut a 0.5.0 release |
+1 from me. I think we could start preparing that. |
|
Looks like everything is alright: approvals OK, CI ok. So, merging this one. |
