Hey Jorn, Appreciate the prompt reply. Yeah that would surely work, we have tried a similar approach. The only concern here is that to make the solution low latency, we want to avoid routing through a message broker. Regards, Sandeep. On Tue, Sep 25, 2018 at 12:53 PM Jörn Franke wrote: >

What is the ultimate goal of this algorithm? There could be already algorithms that can do this within Spark. You could also put a message on Kafka (or another broker) and have spark applications listen to them to trigger further computation. This would be also more controlled and can be done

That’s a pretty major architectural change and would be extremely difficult to do at this stage. On Tue, Sep 25, 2018 at 9:31 AM sandeep mehandru wrote: > Hi Folks, > >There is a use-case , where we are doing large computation on two large > vectors. It is basically a scenario, where we run

Hi Folks, There is a use-case , where we are doing large computation on two large vectors. It is basically a scenario, where we run a flatmap operation on the Left vector and run co-relation logic by comparing it with all the rows of the second vector. When this flatmap operation is running on
