   Hi ,
   I have been working with DSE Solr for past few days .
   I am currently facing an issue specifying unique key in Solr schema.xml .

   In schema, one needs to specify the unique key , which is the row_key in cassandra .
   In my case row_key is been created dynamically , what is the work around for this situation?

   Also I have a column named "id" in my CF which is different from row_key. What i observe is Solr is inserting row_key value in this "id" field . Is there a way to stop Solr inserting in this field , also I dont see this Column in describe CF , once its been indexed by Solr .

   Please help me clear my understanding , as It will help us make decision to use DSE or not .

   Thanks !

   Hi Shruti,
   From my understanding, looks like "id" is reserved word used by DSE in which it maps Cassandra row keys to Solr documents unique id.

   Add the following in your schema file:

   <fields>

   <field name="id" type=<type of your row key> indexed="true" stored="true"/>

   </fields>

   <uniqueKey>id</uniqueKey>

   Hope this helps!

   Regards,
   Srinivas.

   You can't specify the uniqueKey value, it's reserved for DSE internally use.

   Hi ,
   Thanks for replying .

   @srinivasrao - If my row key is a composite key then what type do I specify in schema.xml
   @alexliu - Are you saying that there is no need to provide
   <uniqueKey>id</uniqueKey>
   in schema.xml ?
   As when I tried to do so , I got exception stating I need a uniqueKey .

   Please help me out .

   Thanks!
