Shalin Shekhar Mangar commented on SOLR-11990: ---------------------------------------------- I've attached another approach which does not modify the policy framework directly but instead modifies Suggesters and Collection APIs to maintain the co-location of two collections. This is still a work in progress and has many nocommits. > Make it possible to co-locate replicas of multiple collections together in a > node using policy > ---------------------------------------------------------------------------------------------- > > Key: SOLR-11990 > URL: https://issues.apache.org/jira/browse/SOLR-11990 > Project: Solr > Issue Type: Sub-task > Security Level: Public(Default Security Level.

The policy rules framework > should support this use-case. > Example: Co-locate exactly 1 replica of collection A in each node where a > replica of collection B is present. > {code} > {"replica":">0", "collection":"A", "shard":"#EACH", "withCollection":"B"} > {code} > This requires changing create collection, create shard and add replica APIs > as well because we want a replica of collection A to be created first before > a replica of collection B is created so that join queries etc are always > possible. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
