Gian Merlino	4cc39b2ee7	Alternative groupBy strategy. (#2998 ) This patch introduces a GroupByStrategy concept and two strategies: "v1" is the current groupBy strategy and "v2" is a new one. It also introduces a merge buffers concept in DruidProcessingModule, to try to better manage memory used for merging. Both of these are described in more detail in #2987. There are two goals of this patch: 1. Make it possible for historical/realtime nodes to return larger groupBy result sets, faster, with better memory management. 2. Make it possible for brokers to merge streams when there are no order-by columns, avoiding materialization. This patch does not do anything to help with memory management on the broker when there are order-by columns or when there are nested queries. That could potentially be done in a future patch.	2016-06-24 18:06:09 -07:00
