Subject [jira] [Commented] (SOLR-2193) Re-architect Update Handler
Date Wed, 01 Jun 2011 07:09:48 GMT


Jason Rutherglen commented on SOLR-2193:


And this comment:

Can you elaborate on why you don't think it's implementing NRT? I've tested basic indexing/searching
using wikipedia documents at about 50-100 documents a second, opening a new reader every second.
That felt pretty near-real-time to me, but the phrase is subjective. 


Robert, your statement's confusing.

> 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,
> 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.
