How many Elasticsearch clusters can I deploy with ECK

[Rookie-Zmy]

When deploying an Elasticsearch cluster through ECK, are there any recommendations for the number of clusters managed by a single elastic-operator?

If there are many clusters, do they need to be deployed in multiple namespaces and managed using different elastic-operators?

One operator instance can manage several hundred of clusters. Its capacity is mostly bound by the resources allocated to it and the limitations of the underlying Kubernetes installation. Check #357 (comment).

If you need to manage a large number of clusters, monitor memory usage and adjust the container resources as necessary. You should also increase max-concurrent-reconciles to handle multiple resources at the same time.

Not necessarily, it's up to you how you want to organize your Elastic deployments based on your use case. Just make sure you don't have 2 operators managing the same namespace.
