Hi Max, Good morning! Thanks so much for your review and feedback! I agree on proposal being generic and might not benefit a normal user without having a decent understanding of how autoscaler’s logic works. I had actually planned to contribute some predictive implementations using the custom

Thanks a lot for reviewing the FLIP! Absolutely agree with the point of having some general strategies inside autoscaler itself. cc. @Max since you had similar thoughts on this, I’d love to get your inputs as well on following :)! One of the general strategies that could be beneficial to users c

+1 for this proposal, it allows advanced Users to introduce some specific strategies. Also, if some strategies are general enough, it's better to put them inside the autoscaler. Best, Rui On Sat, Mar 29, 2025 at 3:09 PM wrote: > Hi Venkata, > > Let’s keep this discussion about the FLIP and not

Hi Pradeepta, Thanks for the nice proposal. I am curious, how does the current autoscaler as well as the newly proposed custom evaluator plugin work for batch execution mode? Regards Venkata krishnan On Thu, Mar 20, 2025 at 11:33 PM Pradeepta Choudhury wrote: > Hi Max, Good morning! Thanks so

Hi Gyula, Good morning! Thanks so much for your review and feedback! I absolutely agree about the problem of identifying a job vertex well enough to make more informative decisions using the custom evaluator. Would be more than happy to explore an approach for associating operators with vertex

Hi Pradeepta, Generally, the proposal looks good to me. The only issue I see is that it is fairly generic. On the one hand, it allows plugging in additional evaluation logic into the autoscaler, which allows for many new ways to extend the current autoscaling logic. On the other hand, normal users

Hi! I think this is a very nice proposal, +1 from me! The only practical challenge is to actually be able to identify what job vertex is what in the job graph to make good predictions / feed in external information but this is definitely out of scope here. The autoscaler in general needs to have
