Hi everyone,

I am using Elasticsearch **7.10.0** version on EKS. I need to manually set the heap size since Elasticsearch does not automatically sizes JVM heap until **7.11** version.

It is recommended that the heap size should be no more than 50% of available RAM and no more than 32GB but, are these values equally valid for EKS?

Does this mean that I should not set a _heap size greater than 50% of available RAM visible to the container_?

Any assistance will be greatly appreciated.

Regards!

Yes. This is valid for any Elasticsearch deployment. Note that the threshold is less than 32GB, potentially around 30GB.
