Just tried adding <uniqueKey>id</uniqueKey> while keeping id type= "string" only blank ids are being generated ,looks like the id is being auto generated only if the the id is set to type uuid , but in case of SolrCloud this id will be unique per replica.
Is there a way to generate a unique id both in case of SolrCloud with out using the uuid type or not having a per replica unique id? The uuid in question is of type . <fieldType name="uuid" class="solr.UUIDField" indexed="true" /> On Wed, Nov 12, 2014 at 6:20 PM, S.L <simpleliving...@gmail.com> wrote: > Thanks. > > So the issue here is I already have a <uniqueKey>doctorId<uniquekey> > defined in my schema.xml. > > If along with that I also want the <id></id> field to be automatically > generated for each document do I have to declare it as a <uniquekey> as > well , because I just tried the following setting without the uniqueKey for > id and its only generating blank ids for me. > > *schema.xml* > > <field name="id" type="string" indexed="true" stored="true" > required="true" multiValued="false" /> > > *solrconfig.xml* > > <updateRequestProcessorChain name="uuid"> > > <processor class="solr.UUIDUpdateProcessorFactory"> > <str name="fieldName">id</str> > </processor> > <processor class="solr.RunUpdateProcessorFactory" /> > </updateRequestProcessorChain> > > > On Tue, Nov 11, 2014 at 7:47 PM, Garth Grimm < > garthgr...@averyranchconsulting.com> wrote: > >> Looking a little deeper, I did find this about UUIDField >> >> >> http://lucene.apache.org/solr/4_9_0/solr-core/org/apache/solr/schema/UUIDField.html >> >> "NOTE: Configuring a UUIDField instance with a default value of "NEW" is >> not advisable for most users when using SolrCloud (and not possible if the >> UUID value is configured as the unique key field) since the result will be >> that each replica of each document will get a unique UUID value.
