Ryan McKinley commented on SOLR-269:
------------------------------------
> Some other issues.... how to configure processors for multiple update
> handlers? Perhaps allow configuration of a global default for update handlers
> with no processors specified? That would make it easy to make sure your
> custom processor was used everywhere.
SolrCore could have a single UpdateRequestProcessorFactory that handlers could
use as the default. I'm reluctant to add another plugin layer, but this would
make it easier to share with the CSV update handler and others.
Since its a factory, it will be thread safe across multiple handlers.
Again, I'm reluctant to think about configuring a processor chain in
solrconfig.xml -- we should make the most sensible/extendible default
implementation, but IMO tweeking RequestProcessor functionality should be done
with custom code.

> A simple UpdateRequestProcessor was added to a bloated SOLR-133 commit.
> An UpdateRequestProcessor lets clients plug in logic after a document has
> been parsed and before it has been 'updated' with the index. This is a good
> place to add custom logic for:
> * transforming the document fields
> * fine grained authorization (can user X updated document Y?)
> * allow update, but not delete (by query?)
