Yonik Seeley updated SOLR-2193:
-------------------------------
Description:
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 now do with special casing:
if (directupdatehandler2)
success
else
failish
3. Stop closing the IndexWriter and start using commit (still lazy IW init
though).
4. Drop iwAccess, iwCommit locks and sync mostly at the Lucene level.
5. Keep NRT support in mind.
6. Keep microsharding in mind (maintain logical index as multiple physical
indexes)
