[jira] [Updated] (SOLR-2592) Pluggable shard lookup mechanism for SolrCloud

["Michael Garski (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/SOLR-2592?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Michael Garski updated SOLR-2592:
---------------------------------

    Attachment: dbq_fix.patch

Here is an updated patch that fixes an issue where a delete by query is silently dropped. I have not yet added any additional unit tests for this patch, however all existing unit test pass - which may not be that significant as that did not catch the DBQ issue.

> If the data in a cloud can be partitioned on some criteria (say range, hash, attribute value etc) It will be easy to narrow down the search to a smaller subset of shards and in effect can achieve more efficient search.
