Erick Erickson updated SOLR-880:
--------------------------------

    Description: 
* a core should have an option of loadOnStartup=true|false. default should be 
true

If there are too many cores (tens of thousands) where each of them may be used 
occassionally, we should not load all of them at once. In the runtime I should 
be able to STOP and START a core on demand. A listing command would let me know 
which one is present and what is up and what is down. A stopped core must not 
use any resource


  was:
* We must have an option to STOP and START a core. 
* a core should have an option of loadOnStartup=true|false. default should be 
true
* A list command which can give the names of all cores and some meta 
information like status

If there are too many cores (tens of thousands) where each of them may be used 
occassionally, we should not load all of them at once. In the runtime I should 
be able to STOP and START a core on demand. A listing command would let me know 
which one is present and what is up and what is down. A stopped core must not 
use any resource


        Summary: SolrCore should have a a lazy startup option  (was: SolrCore 
should have a STOP option and a lazy startup option)

Removed STOP from description, functionality is handled by UNLOAD

Broke out the "add a list command" to it's own JIRA, see:
