+## Balancing Groups of Tablets
+
+By default Accumulo evenly spreads each tables tablets across a cluster.  In some 
+situations its advantageous for query or ingest to evenly spreads groups of tablets 
+within a table.  For [ACCUMULO-3439][ACCUMULO-3439] a new balancer was added to evenly 
+spread groups of tablets.  This Apache [blog post][group_balancer] provides more 
+details.
