Embodiment Construction

[0028] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in detail:

[0029] figure 1 It is an example of a database cluster that uses cross-backup to store data slices in the present invention. There are 6 machines in the cluster, and there are 6 data slices in total. Each slice has 1 backup slice. These slices are backed up by cross distributed to each machine in the database cluster.

[0030] figure 2It is a schematic diagram of the distributed database log collection and load adjustment system, and the overall architecture of the system can be seen. The system includes three types of nodes: log collection nodes, load adjustment nodes, and request distribution nodes. The three types of nodes are composed of working nodes and 1-2 backup nodes. Heartbeat detection and correlation are performed between the working nodes and backup nodes. transmission of information. The log collection node is connected to each machin...

Abstract

The invention relates to a distributed database log collection and load regulation system adopting cross backup and a method thereof. According to the system, information related to the load in each machine is collected by utilizing log collection nodes, then the load situation of each machine is assessed by utilizing load regulation nodes so as to obtain a load score, and request distribution nodes give priority of the request to the corresponding machine of the lowest load pressure to perform according to the load score of each machine. The request distribution to the low-load machines can be assisted by utilizing the load information of the machines, and the high-load machines are protected as far as possible so that damage to the machines caused by the fact that the high-load machines continuously receive the request can be avoided and the short plate problem can be greatly avoided.

Description

technical field [0001] The invention relates to the technical field of distributed database storage, in particular to a distributed database log collection and load adjustment system and method using cross-backup. Background technique [0002] In today's era of cloud computing and big data, there is a demand for massive data storage and computing in various fields and industries of society. Facing the pressure and impact of massive data, traditional stand-alone storage systems and stand-alone database systems simply cannot complete the tasks of storage and computing. With the development and maturity of distributed technology, high-speed network transmission technology and parallel computing technology, distributed database has become the mainstream development trend in the current data storage industry. [0003] Most of the distributed databases use the parallel working mode of multiple storage nodes, that is, the mass business data is distributed to each machine of the da...
