Yonik Seeley updated SOLR-139:
------------------------------
Attachment: UpdateProcessor.patch
OK, this patch adds the ability to specify multiple processor factories.
Summary:
- decoupled changing the index from logging... I think it makes it much clearer
how things work (there was much more logging code than anything else). This
also would allow Ryan to add back his incremental timing to a different
processor.
- added SolrInputDocument to AddUpdateCommand, and added some methods
- removed NamedList return from the XML update handler and started passing
SolrQueryResponse around instead (this is more future-proof and flexible)
- removed adding all the ids to the response... (back to 1.2 response format).
We probably shouldn't add ids by default... think of CSV uploading millions of
records, etc.
- An array of factories is kept, and when a processor is instantiated, it is
passed a "next" pointer. An alternative would be to expose a "next factory"
pointer to every factory (any advantage to having the current factory call
getInstance() on the next factory instead of us doing that?)

> It would be nice to be able to update some fields on a document without
> having to insert the entire document.
> Given the way lucene is structured, (for now) one can only modify stored
> fields.
> While we are at it, we can support incrementing an existing value - I think
> this only makes sense for numbers.
> for background, see:
