Shalin Shekhar Mangar updated SOLR-5338: ---------------------------------------- Attachment: SOLR-5338.patch Changes: * Introduces two new methods in CompositeIdRouter {code} public List<Range> partitionRangeByKey(String key, Range range) {code} and {code} public Range routeKeyHashRange(String routeKey) {code} * The collection split action accepts a new parameter 'split.key' * The parent slice is found and its range is partitioned according to split.key * We re-use the logic introduced in SOLR-5300 to do the actual splitting. > 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 > > > 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&split.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 hashes collide. -- This message was sent by Atlassian JIRA (v6.1#6144) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
