Hi i want to use elasticsearch for realtime analysis , for which partitioning scheme is , dumping the indexes in a round robin fashion with a period of 4/2 hrs ( 6/12 shards in total (cycle of 24 hrs)) . Each record contains a time stamp (long) value . For the querying part , the routing parameter is required for optimizing search . in the query there's a time stamp range interval ( t1 , t2 ) , for the interval range ,the result is desired. how should i use this interval to translate into shard routing key ? could somebody please suggest some idea how to achieve this ?
