public class UUIDField extends StrField
This FieldType accepts UUID string values, as well as the special value of "NEW" which triggers generation of a new random UUID.
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.
Using UUIDUpdateProcessorFactory
to generate UUID values when
documents are added is recomended instead.
