摘要：Recently,Energy Management Systems (EMS) have become more integrated and created higher demand of big data processing,thus challenging the real time analysis based on big data technologies. Marz’s Lambda architecture is used for solving problems with querying high amounts of petabyte data. In relation to this,this article presents the Lambda architecture of a particular EMS. The quick and inaccurate results received from the speed layer are replaced by the more precise results of the batch layer. With reference to this,the author proposes a realization of the batch layer based on Hadoop MapReduce technology.
