You are right the correct implementation is here, pending to be reviewed:

This is great, been trying to find the right way to address this config issue for way too long

We have just merged the following PR which addresses the no of open files:

#124

Ideally we'd have good enough defaults for LimitNOFile and such to not have to be concerned with this but adding an ability to override properties in the systemd service makes sense. Should be easy enough to add to the templates for all services e.g. for the broker

[jvalderrama]

It can be done in playbook at https://github.com/confluentinc/cp-ansible/blob/5.1.x/roles/confluent.kafka-broker/defaults/main.yml#L14 , also increase or decrease the memory, for example

 environment:      
      KAFKA_HEAP_OPTS: "-Xmx24g"
      LimitNOFILE: 102400

That won't template the systemd file appropriately, though.

[Service]
Environment=LimitNOFILE=102400

Is different from

[Service]
LimitNOFILE=102400

Quick update that we have a new release shipping shortly which will address this.
