Subject [jira] [Commented] (SOLR-5017) Allow sharding based on the value of a field
Date Tue, 09 Jul 2013 13:17:50 GMT

    [ https://issues.apache.org/jira/browse/SOLR-5017?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13703246#comment-13703246
] 

Noble Paul commented on SOLR-5017:
----------------------------------

if a collection is created with the shardField value, it is a required param for all docs.If
the field is null the document addition fails. No more lookup for "!" anymore.

> We should be able to create a collection where sharding is done based on the value of
a given field
> collections can be created with shardField=fieldName, which will be persisted in DocCollection
in ZK
> implicit DocRouter would look at this field instead of _shard_ field
> CompositeIdDocRouter can also use this field instead of looking at the id field.
