> Experiment with Jenkins Worker VM Sizes and # executors
> -------------------------------------------------------
>
> Key: BEAM-10256
> URL: https://issues.apache.org/jira/browse/BEAM-10256
> Project: Beam
> Issue Type: Improvement
> Components: build-system
> Reporter: Tyson Hamilton
> Priority: P3
> Labels: Jenkins, infra, infrastructure, jenkins
>
> When on the new Apache infra for Jenkins we should revisit the size of our
> VMs. Currently we use n1-highmem-16 but this may be wasteful since only 2
> executors are running on each worker.
>
> One option is to increase the number of executors on each worker, say to 8,
> so each executor has 2 vcpus. The upper limit is our desired thread
> parallelism per executor (i.e. tests) and the memory required for each.
> Another option is to downsize the VM to a n1-highmem-4 and keep 2 executors.
> There are probably others, we should do some analysis to see what makes sense.
