-------------------------------------
Summary: Experiment with Jenkins Worker VM Sizes
Key: BEAM-10256
URL: https://issues.apache.org/jira/browse/BEAM-10256
Project: Beam
Issue Type: Bug
Components: build-system
Reporter: Tyson Hamilton
Assignee: Tyson Hamilton
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.
