[jira] [Commented] (NUTCH-1047) Pluggable indexing backends
[ https://issues.apache.org/jira/browse/NUTCH-1047?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13066179#comment-13066179 ]
Lewis John McGibbney commented on NUTCH-1047:
---------------------------------------------
I think the suggestion of generic/example/template map/reduce jobs would be an excellent addition. This is a great idea. In my opinion it would reduce the barrier for entry to users inexperienced in setting up jobs.
My interest in your last point is a question which I suppose is wide open to discussion. What end-points (generally speaking) are we going to support and formally represent as pluggable entities? What criteria do we make decisions based on?

> One possible feature would be to add a new endpoint for indexing-backends and make the indexing plugable. at the moment we are hardwired to SOLR - which is OK - but as other resources like ElasticSearch are becoming more popular it would be better to handle this as plugins. Not sure about the name of the endpoint though : we already have indexing-plugins (which are about generating fields sent to the backends) and moreover the backends are not necessarily for indexing / searching but could be just an external storage e.g. CouchDB. The term backend on its own would be confusing in 2.0 as this could be pertaining to the storage in GORA. 'indexing-backend' is the best name that came to my mind so far - please suggest better ones.
> We should come up with generic map/reduce jobs for indexing, deduplicating and cleaning and maybe add a Nutch extension point there so we can easily hook up indexing, cleaning and deduplicating for various end-points.
