Distributed database architecture based on shared memory and multiple processes and implementation method thereof

Abstract

The invention discloses a distributed database architecture based on a shared memory and multiple processes and an implementation method, and belongs to a distributed database architecture, which comprises distributed database nodes, a distributed database built-in system shared memory unit and a system process unit, the system shared memory unit comprises a task stack information module and a shared cache module; a plurality of process tasks is arranged in the task stack information module; the process tasks are multi-purpose system information in the system process task information, and eachpiece of system information corresponds to one process task; a system shared memory unit is used at a distributed database node, so that the connection number of users in the distributed database architecture does not correspond to processes or threads, and the process or thread number of the whole node is not increased due to the increase of the connection number of the users; therefore, the slow response speed of the system due to excessive instantaneous user connection numbers is effectively avoided, and the performance of the system is not affected.

Description

technical field [0001] The present invention relates to a distributed database architecture, more specifically, the present invention mainly relates to a distributed database architecture based on shared memory and multi-process and its implementation method. Background technique [0002] At present, applications that require high concurrency are basically implemented through connection middleware. The connection middleware needs to do a lot of analysis and merging processing. After the user's query request is analyzed, it is distributed to the corresponding stand-alone database for processing, and the query results are merged. After processing, it is sent to the previous application, so there is a performance bottleneck in the middleware. In order to solve this problem, the middleware must also be developed into a distributed system, which leads to each layer being a distributed architecture system, which is very important for management and operation and maintenance. It ha...

Problems solved by technology

[0003] One of the purposes of the present invention is to provide a distributed database architecture and implementation method based on shared memory and multi-process in view of the above-mentioned deficiencies, in order to solve the problem that an abnormality in a connection of a similar database in the prior art will affect all other nodes of the node. Connection, technical issues such as the maximum number of connections supported by the node is limited
