[Priyanka Saggu, sreeram-venkitesh] CEL cost discussion for KEP 4595: CEL for CRD additionalPrinterColumns
We want to discuss feedback from the KEP PR regarding the CEL cost limit.
Conclusion:
Ideal would be equivalent performance to jsonpath, up to 2x latency cost could be acceptable, more than 2x is likely an implementation blocker (cel v/s jsonPath)


[sreeram-venkitesh] Adding CEL formats to CRDs (k/k#130639)
I’ve opened a PR to kube-openapi adding Quantity to pkg/validation/strfmt. I’m not sure if importing k8s.io/apimachinery/pkg/api/resource in kube-openapi is the correct way to make Quantity work here.
I have also opened a PR in k/k adding Quantity to the CRD formats as well as to SchemaDeclType and UnstructuredToVal. This works locally when I use my kube-openapi branch linked above.
k/kube-openapi PR: https://github.com/kubernetes/kube-op...
k/k PR: https://github.com/kubernetes/kuberne...
Update before call: Went through the comments from Cici and Jordan. Since we cannot import apimachinery/resource, can we copy over the logic for Quantity to kube-openapi so that we can use the ParseQuantity method in validation/strfmt?
