Subject [jira] Created: (SOLR-2193) Re-architect Update Handler

Re-architect Update Handler
---------------------------

                 Key: SOLR-2193
                 URL: https://issues.apache.org/jira/browse/SOLR-2193
             Project: Solr
          Issue Type: Improvement
            Reporter: Mark Miller
             Fix For: Next


The update handler needs an overhaul.

A few goals I think we might want to look at:

1. Cleanup - drop DirectUpdateHandler(2) line - move to something like UpdateHandler, DefaultUpdateHandler
2. Expose the SolrIndexWriter in the api or add the proper abstractions to get done what we
know do with special casing:
if (directupdatehandler2)
  success
 else
  failish
3. Stop closing the IndexWriter and start using commit.
4. Drop iwAccess, iwCommit locks and sync mostly at the Lucene level.
5. Keep NRT support in mind.
