             Summary: Split shards by a route key
                 Key: SOLR-5338
                 URL: https://issues.apache.org/jira/browse/SOLR-5338
             Project: Solr
          Issue Type: Improvement
          Components: SolrCloud
            Reporter: Shalin Shekhar Mangar
            Assignee: Shalin Shekhar Mangar
             Fix For: 4.6, 5.0


Provide a way to split a shard using a route key such that all documents of the specified route key end up in a single dedicated sub-shard.

Example:
Assume that collection1, shard1 has hash range [0, 20]. Also that route key 'A!' has hash range [12,15]. Then invoking:
{code}
/admin/collections?action=SPLIT&collection=collection1&shard=shard1&split.key=A!
{code}
should produce three sub-shards with hash range [0,11], [12,15] and [16,20].

Now the sub-shard dedicated to documents for route key 'A!' can be scaled separately.
