Range query in P2P system is mainly made by establishing index, such as B+ tree or DST. However when the number of nodes in the system and the amount of data in a single node increases significantly, the above traditional index will become extremely large so it will affect the query efficiency. In the present, enterprises require effective data analysis when making some important decisions, such as user's consumption habits deriving from analyzing user data. This paper aims at optimization of range query in big data. This algorithm introduces MapReduce in P2P system and organizes files by P-Ring in different nodes.
