--------------------------------------

Thanks Shalin! This will be a great improvement in terms of how people use the 
system - Users don't have to think of making rules to distribute load unless 
they are doing something very specific.

 
{quote}However, autoAddReplicas implementation does not use this flag but maybe 
it should? Either that or all the default rules should be made strict=fal

...
# Each shard cannot have more than one replica on the same node if 
possible{quote}
Maybe this policy shoud not be strict=false but the other two policies could be 
?

> Add a default cluster policy

> bq. 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:
> {code}
> # 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}
> {code}
