Mass real-time data distributing method and mass real-time data access method

Abstract

The invention discloses a mass real-time data distributing method and a mass real-time data access method. The mass real-time data distributing method comprises the following steps of calculating a first hash value of each real-time database node by utilizing a hash function, and configuring the obtained first hash value onto a circle; calculating a second hash value of the test-point information by utilizing the hash function; mapping the second hash value onto the circle to be matched with the first hash value, storing the data of the second hash value onto a first database node which is matched on the circle; and storing the data of the second hash value onto a first database node on the circle at the beginning of the searching if the second hash value cannot find a matched database node after searching one turn on the circle. According to the mass real-time data distributing method and the access method, the re-distribution of measured points on each database node can be maximally inhibited, the nonuniformity for distributing the measured points on each database node can be effectively prevented, the re-distribution of the database nodes when the database nodes are increased or reduced can be maximally reduced, the access time also can be greatly shortened through the rapid and convenient access steps, and the access efficiency is greatly increased.

Description

[0001] technical field [0002] The invention relates to a massive real-time data distribution method and an access method thereof. [0003] Background technique [0004] The data processed by the real-time database are the measurement points and the real-time data collected in the process industry. There is no strong logical connection between the measurement points and their real-time data. It is this characteristic that makes the real-time database particularly suitable Carry out distributed deployment and application. [0005] At present, there are relatively mature real-time database products at home and abroad, and these products can also be deployed in a distributed manner. The usual deployment mode is as follows figure 1 As shown, the real-time database is distributed and deployed on each server (DB-1, DB-2, ..., DB-M) in the network environment, and each application (APP-1, APP-2, ..., APP-N) accesses each database server to obtain or modify data according to i...

Problems solved by technology

As the scale of real-time data becomes larger and the sources of real-time data become more and more diverse, the requirements for real-time data application systems become higher and higher and more complex, which will greatly increase the difficulty and complexity of application development and maintenance. degree, and this approach does not conform to the layered construction principle of the application system, which will eventually lead to the ending that the application system cannot be deployed at all.
