Subject [jira] [Commented] (SOLR-3154) SolrJ CloudServer should be leader and network aware when adding docs
Date Tue, 31 Jul 2012 16:07:35 GMT

bq. Yonik?

Chatted with Mark a bit about this - I think it's fine.  We should just make sure to make
it's a good hash (i.e. not String.hashCode ;-) and define it well so it can be implemented
in other languages/clients.

> It would be good when indexing if the SolrJ CloudServer was leader aware so that we could
avoid doing an extra hop for the data.  It would also be good if one could easily set things
up based on data locality principles.  This might mean that CloudServer is aware of where
on the network it is and would pick leaders that are as close as possible (i.e. local, perhaps.)
 This would come in to play when working with tools like Hadoop or other grid computing frameworks.
