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

Imagine having 10's of 1000's of  such small files in a directory

> Persisting and loading details from one xml is fine if the no:of cores are small and
the no:of cores are few/fixed . If there are 10's of thousands of cores in a single box adding
a new core (with persistent=true) becomes very expensive because every core creation has to
write this huge xml. 
> Moreover , there is a good chance that the file gets corrupted and all the cores become
unusable . In that case I would prefer it to be stored in a centralized DB which is backed
up/replicated and all the information is available in a centralized location. 
> We may need to refactor CoreContainer to have a pluggable implementation which can load/persist
the details . The default implementation should write/read from/to solr.xml . And the class
should be pluggable as follows in solr.xml
> {code:xml}
> <solr>
>   <dataProvider class="com.foo.FooDataProvider" attr1="val1" attr2="val2"/>
> </solr>
> {code}
> There will be a new interface (or abstract class ) called SolrDataProvider which this
class must implement
