What memory limit should i set for etcd?

[V0idk]

What would you like to be added?

I am deploy etcd by k8s pod, but i have an oom probelm when i set memory limit 12Gi:

apiVersion: v1
kind: Pod
    resources:
      limits:
        cpu: "4"
        memory: 12Gi

etcd command is:

etcd --snapshot-count=10000 --auto-compaction-retention=24 --max-request-bytes=10485760 --quota-backend-bytes=858993459 ...

my question is what is the proberly memory limit for the above command?

Is limit = quota-backend-bytes + ? ok? but why 12Gi is not enough for quota-backend-bytes 8g?

or Is limit = quota-backend-bytes * 2 ok?

Why is this needed?

etcd memory usage depends mostly on how the API is used and cannot be guessed. For example you can make concurrent list requests for all keys, requiring etcd to allocate Gigabytes of memory per request (also applies to K8s :)).
