Shreejay commented on SOLR-2592:
--------------------------------
Thanks for the quick reply. For some reason it does not seem to be working on
my local machine. In the above example is foo_field the composite field? or the
field on which the hash is done? But like u mentioned the "clause" field only
matters during deletes. I am trying to add documents and they are not going to
same shards.
I have created a composite unique key (unique_id = guidid + "_" + anotherID)
guidid is a string guid. My schema file has these two lines.
<field name="unique_id" type="string" indexed="true" stored="true"
required="true" />
<uniqueKey>unique_id</uniqueKey>
In my Solrconfig file under <config> i have added the below lines.
<shardKeyParserFactory
class="org.apache.solr.common.cloud.CompositeIdShardKeyParser">
<str name="clause">guidid</str>
<bool name="clauseRequired">false</bool>
</shardKeyParserFactory>
Am I missing configuring anything else?
I have applied the SOLR-2592_r1384367.patch on branch_4x and the build was
successful.

> If the data in a cloud can be partitioned on some criteria (say range, hash,
> attribute value etc) It will be easy to narrow down the search to a smaller
> subset of shards and in effect can achieve more efficient search.
