Subject [jira] [Commented] (SOLR-2593) A new core admin action 'split' for splitting index
Date Tue, 14 Feb 2012 01:45:00 GMT


Andrzej Bialecki  commented on SOLR-2593:

Jason, see LUCENE-2632 for a possible way to implement this at the Lucene level. Splitting
into arbitrary parts so far required multiple passes over input data, using the approach of
tee/filter codecs it's possible to do this in one pass over the input data.

> If an index is too large/hot it would be desirable to split it out to another core .
> This core may eventually be replicated out to another host.
> There can be to be multiple strategies 
> * random split of x or x% 
> * fq="user:johndoe"
> example :
> action=split&split=20percent&newcore=my_new_index
