   -   When using `nats-js-kv` it is recommended to set `OC_CACHE_STORE_NODES` to the same value as `OC_EVENTS_ENDPOINT`. That way the cache uses the same nats instance as the event bus.
   -   When using the `nats-js-kv` store, it is possible to set `OC_CACHE_DISABLE_PERSISTENCE` to instruct nats to not persist cache data on disc.
