> As SolrCloud is now used at fairly large scale, most users end up writing their own cluster
management tools. We should have a framework for cluster management in Solr.
> In a discussion with [~noble.paul], we outlined the following steps w.r.t. the approach
to having this implemented:
> * *Basic API* calls for cluster management e.g. utilize added nodes, remove a node etc.
These calls would need explicit invocation by the users to begin with.
> * *Metrics* and stats tracking e.g. qps, etc. These would be required for any advanced
cluster management tasks e.g. *maintain a qps of 'x'* by *auto-adding a replica* (using a
recipe) etc. We would need collection/shard/node level views of metrics for this.
> * *Recipes*: combination of multiple sequential/parallel API calls based on rules. This
would be complicated specially as most of these would be long running series of tasks which
would either have to be rolled back or resumed in case of a failure.
> * *Event based triggers* that would not require explicit cluster management calls for
end users.
