Subject [jira] [Commented] (SOLR-2193) Re-architect Update Handler
Date Tue, 31 May 2011 04:35:48 GMT


Mark Miller commented on SOLR-2193:

Heh. Golden Goose. There are geese on the farm I grew up next too. They never needed much
protected - they ran in a pack and charged around fearless.

If I had a Golden Goose (and I'm still looking if you know anyone), I'd choose to protect
it with like a knife or a gun rather than code :)

This is a meritocracy. Those with merit impart it on the deserving. There are a wide variety
of those with merit from a diverse set of companies. So others that deserve merit can be sure
to get a fair shake over time. Those without merit...well...they will be what they be.

> 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.
