SOLR-5338: Split shards by a route key using split.key parameter
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
Attachments: SOLR-5338.patch, SOLR-5338.patch, SOLR-5338.patch
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=SPLITcollection=collection1split.key=A!
{code}
should produce three sub-shards with hash range [0,11], [12,15] and [16,20].
Specifying the source shard is not required here because the route key is
enough to figure it out. Route keys spanning more than one shards will not be
supported.
Note that the sub-shard with the hash range of the route key may also contain
documents for other route keys whose hash ranges overlap.

Yonik Seeley commented on SOLR-5338:
bq. Would you mind reviewing the new CompositeIdRouter methods?
Yeah, these make sense. You could optionally not throw this error:
+ throw new IllegalArgumentException(Route key must be a composite id);
and just return a range that covers the single hash code of the ID.
