public class UUIDUpdateProcessorFactory extends UpdateRequestProcessorFactory
An update processor that adds a newly generated UUID value
to any document being added that does not already have a value in the
specified field.
In the example configuration below, if a document does not contain a value
in the id field, a new UUID will be generated
and added as the value of that field.
<processor class="solr.UUIDUpdateProcessorFactory"> <str name="fieldName">id</str> </processor>
If field name is omitted in processor configuration,
then @{link org.apache.solr.schema.IndexSchema#getUniqueKeyField()}
is used as field and a new UUID will be generated
and added as the value of that field. The field type of the uniqueKeyField
must be anything which accepts a string or UUID value.
