使用bulk API 增加入库速度
初次索引的时候，把 replica 设置为 0
增大 threadpool.index.queue_size 1000
增大 indices.memory.index_buffer_size: 20%
index.translog.durability: async –这个可以异步写硬盘，增大写的速度
增大 index.translog.flush_threshold_size: 600MB
增大 index.translog.flush_threshold_ops: 500000

另外一部分，则需要先做聚类、分类处理，将聚合出的分类结果存入ES集群的聚类索引中。数据处理层的聚合结果存入ES中的指定索引，同时将每个聚合主题相关的数据存入每个document下面的某个field下。
