Subject [Solr Wiki] Update of "LotsOfCores" by ShalinMangar
Date Thu, 29 Oct 2009 09:21:19 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Solr Wiki" for change notification.

The "LotsOfCores" page has been changed by ShalinMangar.
The comment on this change is: Added SOLR-1531.


    * [[|SOLR-1106]] - Pluggable CoreAdminHandler
(Action ) architecture that allows for custom handler access to CoreContainer / request-response
    * [[|SOLR-1416]] - Reduce contention in
    * [[|SOLR-1530]] - Open IndexSearcher lazily
+   * [[|SOLR-1531]] - Provide an option to
remove the data directory on core unload
  Other features which may be needed for such a system include:
   * Provide a way to partition data directories into multiple "bucket" directories. For example,
instead of creating 10,000 data directories inside one base data directory, Solr can assign
a core to one of 4 base directories, thereby distributing them.
-  * Provide a way to completely remove a core - Currently the unload command keeps the core's
data on disk even though the details of the core is deleted from configuration. Solr can have
an option of cleaning the data directory on unload of a core
   * Changes to SolrJ for new start/stop commands and better error codes/messages.
