What is Partition Split At DolrCloud?

[Furkan KAMACI <fu...@gmail.com>]

I was reading here: http://wiki.apache.org/solr/NewSolrCloudDesign
There says something about:

*Split_partition* : (params : partitionoptional). The partition is split
into two halves. If the partition parameter is not supplied, the partition
with the largest number of documents is identified as the candidate.

What is that partition split? Is it something like that that resolved

The NewSolrCloudDesign document is not accurate. It was initially created
to record ideas but the implementation of SolrCloud has evolved to be
different from the design in that document.

SOLR-3755 splits a given partition and creates two partitions of half the
hash range of the parent partition. Look at the "SPLITSHARD" section at
http://wiki.apache.org/solr/SolrCloud#Managing_collections_via_the_Collections_API

I'm going to add more wiki documentation on how this feature works in a
couple of days.
