Subject [jira] [Commented] (SOLR-3858) Doc-to-shard assignment based on "range" property on shards
Date Mon, 29 Oct 2012 14:38:13 GMT

    [ https://issues.apache.org/jira/browse/SOLR-3858?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13486052#comment-13486052
] 

Dmitry Kan commented on SOLR-3858:
----------------------------------

Is there an idea of how the range property should be defined? Something like this in solrconfig:

<docIdToShardAssignment>
   <rangeField>FieldName</rangeField> <!-- e.g. a date field -->
   <rangeStart>20121001</rangeStart> <!-- granularity probably should be customizable
-->
   <rangeEnd>20121031</rangeEnd>
</docIdToShardAssignment>

?

Does this property (if defined) turn the sharding scheme into logical sharding?

> Anything that maps a document id to a shard should consult the ranges defined on the
shards (currently indexing and real-time get).
