[~varunthacker] commented on SOLR-12739:
We should also ship with some default policies - "Don't allow more than one replica of a shard on the same JVM" , "Distribute cores across the cluster evenly" , "Distribute replicas per collection across the nodes"
This issue is about adding these defaults. I propose the following as default cluster policy:
# Each shard cannot have more than one replica on the same node if possible {"replica": "<2", "shard": "#EACH", "node": "#ANY", "strict":false} # Each collections replicas should be equally distributed amongst nodes {"replica": "#EQUAL", "node": "#ANY", "strict":false} # All cores should be equally distributed amongst nodes {"cores": "#EQUAL", "node": "#ANY", "strict":false}
