Ryan McKinley commented on SOLR-308:
------------------------------------
If I'm following correct, this is a FieldType that generates a UUID regardless
of the input value:
public Field createField(SchemaField field, String externalVal, float
boost) {
// We ignore the external value and have our own
return super.createField(field, UUID.randomUUID().toString(),
boost);
}
What is a use case for that?
If you are looking for something like the sql auto increment, it might be a
good candidate for the new fangled 'UpdateRequestProcessor' -- this could check
if the input document has a uniqueKey - if not, add one and add the new value
to the response.
