Subject [jira] [Updated] (SOLR-3755) shard splitting
Date Thu, 30 Aug 2012 21:56:08 GMT


Yonik Seeley updated SOLR-3755:

    Attachment: SOLR-3755.patch

OK, here's a patch with minimal functionality that seems to work (no tests yet though):

curl "http://localhost:8983/solr/admin/cores?core=collection1&action=SPLIT&path=/tmp/1&path=/tmp/2"

That command will split the index in two.  It will not consider the existing "range" of the
current core or create new cores or anything like that yet... it only splits the index and
writes them in separate directories.

> We can currently easily add replicas to handle increases in query volume, but we should
also add a way to add additional shards dynamically by splitting existing shards.
