--------------------------------------------------

   '''Horizontal v.s. Vertical Partition'''<<BR>>
   In database jargon a "horizontal partition" splits record sets into multiple stores, while
a ''vertical partition'' splits each row into multiple pieces and stores each piece in a separate
database, cross-connected by the primary key for the record. DistributedSearch provides a
''horizontal partition''. There is no implementation of a vertical partition across indexes.
  
+  '''MultiTiered'''<<BR>>
+  If one places too many servers per proxy/shard multiplexer, then the proxy server can become
overloaded.  Multiple tiers of Solr distributed proxy search servers, scales the per server
load out to N tiers. See SOLR-1477
+ 
+ '''KattaIntegration'''
+   Hadoop based RPC enables potentially better scalability compared with HTTP.  See SOLR-1395
+ 
+ '''HadoopIndexing'''
+   SOLR-1301 implements Hadoop based indexing for Solr.
