Embodiment Construction

[0032] The technical solutions in the embodiments of the present invention will be described clearly and in detail below with reference to the drawings in the embodiments of the present invention. The described embodiments are only some of the embodiments of the invention.

[0033] The technical scheme that the present invention solves the problems of the technologies described above is:

[0034] The present invention adds a load monitor module on the original MongoDB system framework, and is responsible for periodically and dynamically monitoring the cpu utilization rate N of each server CPU , Memory utilization N MEMORY , Bandwidth utilization N BANDWIDTH(In order to avoid affecting system performance due to obtaining too many indicators, only these three are considered). and set weights for them respectively.

[0035] After many experiments, it was found that cpu utilization and memory (momery) utilization have a greater impact on the performance of the server, so the s...

Abstract

The invention discloses a MongoDB-based load balancing optimization system, the MongoDB-based load balancing optimization system comprises a MongoDB system, data of the MongoDB is stored in each slice, the data is divided into data blocks of certain size and then placed in each server, and when the number of the data blocks in each server is not balanced, load balancing is realized through a balancer module; for the MongoDB-based load balancing optimization system, one load monitor module is added on the MongoDB system framework and is in charge of periodically and dynamically monitoring a cpuutilization rate NCPU, a memory utilization rate NMEMORY and a bandwidth utilization rate NBANDWIDTH of each server, and respectively setting a cpu utilization rate weight k1, a memory utilization rate weight k2 and a bandwidth utilization rate weight k3; and the server comprehensively considers adjustment according to real-time judgement on whether overloading exists and operation heat of the data blocks, and thus, MongoDB dynamic load balancing is realized. With the system and the method provided by the invention, a resource utilization rate of the server is maximized, and MongoDB dynamic load balancing is realized.

Description

technical field [0001] The invention belongs to the field of data processing performance optimization of databases, in particular to a method for improving load balancing, which improves the high concurrent reading and writing capabilities of databases. Background technique [0002] Due to the advent of the era of big data and the rapid development of cloud storage technology, people's daily life and various scientific experiments have generated massive amounts of data. For how to effectively and quickly store and extract these massive data, traditional relational databases have exposed many difficult problems. Especially in the face of high concurrent read and write requests, fast access to massive data, efficient storage, and high scalability of the database, it is difficult to meet the needs. [0003] Therefore, the non-relational database NoSql came into being. NoSql database is famous for supporting massive data, high availability, and high scalability, and solves the...
