Summary: Add support for setting GOMEMLIMIT in Helm chart
Key: YUNIKORN-3000
URL: https://issues.apache.org/jira/browse/YUNIKORN-3000
Project: Apache YuniKorn
Issue Type: Improvement
Components: release, release-notes
Reporter: Craig Condit
Assignee: Craig Condit
As of Go 1.19, Go supports reading a {{GOMEMLIMIT}} environment variable to
limit the amount of RAM the process will use before garbage collecting. This is
a soft limit, but helps constrain resource usage and can help avoid being
OOMKilled by Kubernetes. Since we set our existing memory request to 1 GiB, and
limit to 2 GiB, I propose setting the default {{GOMEMLIMIT}} value to 1.5 GiB.
This allows for non-GC overhead plus transient spikes, and should keep us well
under the threshold for being OOMKilled.
