non-indexable SOLR schema

Riak does not in any way rely on solr for its KV operations. Not sure where you are seeing that or what code you are looking at but you can define bucket types, activate them without ever touching solr.  The basic bucket type set up instructions can be found here: http://docs.basho.com/riak/latest/dev/advanced/bucket-types/.

How to do that?

For what I have seen, to use these special data types you need to create a bucket under a bucket_type; and this bucket type is created following an index so data gets indexed in Solr.

You do not have to set up Yokozuna (yz) to be able to use counters, sets, maps in Riak. Those types can be used independently via the Riak key value store. You only need to set up the indexes if you were to search for data via yz or search 2.0. And in that case, you can remove the generic mappings, keep the _yz specific ones and then explicitly add the fields you want to index/search on.

Hi all,

To be able to use counters/sets/maps in Riak I have to store the object into a defined bucket_type indexed via SOLR.

However, this will require extra disk space as data will be indexed (if using the default schema). Can I create a custom schema "ignoring" all fields so nothing is indexed? I don't need to use Riak Search on these objects, as I always know the KEY to fetch them. A schema like this would work? ( I guess that I can not put [ indexed="false" ] in the "_yz*" fields required by Riak, right? Or is it possible to not index that data either? )

—+—+—+—+—+—+—+—+—+—+—+—+—+—+—+—+—+—+—+—+—+—+—+—+—+—
<?xml version="1.0" encoding="UTF-8" ?>
<schema name="schedule" version="1.5">
 <fields>
   <dynamicField name="*" type="ignored" />
   <!-- All of these fields are required by Riak Search -->
   <field name="_yz_id"   type="_yz_str" indexed="true" stored="true"  multiValued="false" required="true"/>
   <field name="_yz_ed"   type="_yz_str" indexed="true" stored="false" multiValued="false"/>
   <field name="_yz_pn"   type="_yz_str" indexed="true" stored="false" multiValued="false"/>
   <field name="_yz_fpn"  type="_yz_str" indexed="true" stored="false" multiValued="false"/>
   <field name="_yz_vtag" type="_yz_str" indexed="true" stored="false" multiValued="false"/>
   <field name="_yz_rk"   type="_yz_str" indexed="true" stored="true"  multiValued="false"/>
   <field name="_yz_rt"   type="_yz_str" indexed="true" stored="true"  multiValued="false"/>
   <field name="_yz_rb"   type="_yz_str" indexed="true" stored="true"  multiValued="false"/>
   <field name="_yz_err"  type="_yz_str" indexed="true" stored="false" multiValued="false"/>
 </fields>

 <uniqueKey>_yz_id</uniqueKey>

 <types>
    <fieldtype name="ignored" stored="false" indexed="false" multiValued="true" class="solr.StrField" />
    <!-- YZ String: Used for non-analyzed fields -->
    <fieldType name="_yz_str" class="solr.StrField" sortMissingLast="true" />
 </types>
</schema>
—+—+—+—+—+—+—+—+—+—+—+—+—+—+—+—+—+—+—+—+—+—+—+—+—+—

Another question, can I use the [ compressed="true" ] to save disk space? in both <dynamicField name="*" type="ignored" /> and "_yz*" fields?

Thanks,
Alex
