Embodiment Construction

[0030] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0031] The present invention adopts an in-memory database cluster to perform load balancing on access requests initiated by the client 10. The in-memory database cluster includes multiple cluster groups 40, and each cluster group 40 is composed of multiple in-memory database instances that are mirror images of each other. Such as Figure 8 Shown is a schematic diagram of the structure of the memory database cluster. According to an embodiment of the present invention, a load balancing method is provided to solve the problem in the prior art that a single point of failure cannot be effectively dealt with when processing large data and high concurrency. Such as figure 1 As shown, it is a work flow chart of the load bal...

Abstract

The invention discloses a load equalizing method and system. The method comprises the steps of calculating the optimal group corresponding to the access request through a load equalizing engine based on the consistent hash algorithm and according to the group management the overall operation state of the in-memory database group provided by a monitoring device and the number of the access request; sending the access request distributed by a client to the optimal group to respond. According to the method and the system, the in-memory database manner is adopted, so that the performance influence caused by I / O bottleneck of a magnetic disk of the current computer system can be avoided; in addition, the risk and shortages of single-point failure can be avoided by the ground redundancy method, and therefore, the problem that single-point fault cannot be effectively handled in case of handling big data and high concurrence in the fields of data acquiring of an intelligent power grid and a power Internet of Things can be solved well.

Description

technical field [0001] The present invention relates to the technical field of intelligent power utilization in the communication field, and in particular, to a load balancing method and system. Background technique [0002] In recent years, with the rapid development of smart grid and Internet of Things technology, smart sensing technology has been more and more widely used in power generation, power transmission, power transformation, power distribution, power consumption, and dispatching. Big data and high concurrent data processing technology supporting intelligent sensing applications is one of the keys to the application of the entire intelligent sensing technology. [0003] At present, in the field of smart grid and electric power Internet of Things data collection, solving big data and high concurrency problems is mainly through relational database clusters and multi-threading technology in a multi-core environment; at the same time, the gradual application of single...
