I don't know about SOLR-5017, but why don't you want to use parent_id as a shard key?
So if you've got a doc with a key of "abc123" and a parent_id of 456, just use a key of "456!abc123" and all docs with the same parent_id will go to the same shard. We're doing something similar and limiting queries to the single shard that hosts the relevant docs by setting shard.keys=456! on queries. -Greg On Wed, Aug 28, 2013 at 10:04 AM, adfel70 <adfe...@gmail.com> wrote: > Hi > I'm looking into allowing query joins in solr cloud. > This has the limitation of having to index all the documents that are > joineable together to the same shard. > I'm wondering if SOLR-5017 > <https://issues.apache.org/jira/browse/SOLR-5017> would give me the > ability to do so without implementing my own routing mechanism? > > If I add a field named "parent_id" and give that field the same value in all > the documents that I want to join, it seems, theoretically, that it will be > enough. > > Am I correct? > > Thanks. > > > > > > -- > View this message in context: > http://lucene.472066.n3.nabble.com/Question-about-SOLR-5017-Allow-sharding-based-on-the-value-of-a-field-tp4087050.html > Sent from the Solr - User mailing list archive at Nabble.com.
