Simon Willnauer commented on SOLR-2193:
---------------------------------------

Jason, your action on this issue is not appropriate and with my PMC Hat on I can't tolerate
this! I want remind you to move back to an appropriate tone and help out rather than randomly
-1. I don't see any political issues here neither is the -1 appropriate. You have done lots
of realtime work and mark seems to be pretty open to comments too so get back to technical
discussion. If you have any general issues feel free to raise them on dev@l.a.o

> 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)
> 7. Address the current issues we face because multiple original/'reloaded' cores can
have a different IndexWriter on the same index.
