Reviewed these materials. Leads to a question/input... Background: Long-ago (cpu-cycles billing era) I committed to using TaskQueues (TQ) to minimize on-line handler latency. So, I am exposed to issues related to unpredictable TQ task start times. (Fortunately to date I have not been affected, but figure it is a matter of time.) Long ago asked that developers be given the option of configuring a high-performance TQ which would not be affected by unpredictable start times. The recent thread on this issue suggests I am not alone in these TQ architecture decisions.
Question: The video covered upcoming changes implementing Application>>Server>>Version architecture enabling developers to control performance settings beyond today's "default version only" setup. Looks great. Can I set up a Server>>Version solely to handle my "high-performance" TQ tasks in such a way that task execution will be more predictable? My hope is that if I setup a version that only received my "high performance" TQ tasks, it will not be affected by the task start variability because it will have nothing else to do but TQ tasks. Input: If the answer is "No", please consider a App>>Server>>Version yaml setting by which the developer specify a version which will prioritize immediate handling of TQ tasks (i.e. as if the TQ task was an on-line handler call). If I have mis-interpreted the video: My apologies and please forgive me wasting your time.
