A high-availability framework system for single-point heterogeneous data storage and its implementation method

Abstract

The invention discloses a high-availability framework system with a single-point heterogeneous data storage function. The high-availability framework system comprises a client type base ti-a59-client, a heterogeneous data conversion and storage service module ti-a59-builder, a data write operation log service module ti-a59-log-srv, a data queue framework ti-queue, a message queue service module MQ Server, a single-point deployment type heterogeneous data storage server Single Server DataStore, a write request log service data storage module Write Log DataStore, and a write request control log data storage module Ctrl Log DataStore. The invention also discloses a method for realizing the system. The high-availability framework system has the advantages that the property of high-availability support of single-point deployment storage of the existing framework is realized, the stronger cross-platform deployment capability is realized, multiple data storage types are supported, the data synchronizing between heterogeneous data is supported, and the important properties of data backup and data restoration functions under the condition of support node faults are supported.

Description

technical field [0001] The invention belongs to the field of computers, and relates to a high-availability framework for data storage, in particular to a high-availability framework system for single-point heterogeneous data storage; in addition, the present invention also relates to the high-availability framework system for single-point heterogeneous data storage Implementation. Background technique [0002] The existing technology is a high-availability framework for single-point deployment data storage developed by a foreign team (see figure 1 ). [0003] figure 1 , each module is described as follows: [0004] 1.dyno: An existing high-availability framework for single-point storage. [0005] 2. dyno-client: the client class library of the existing framework. [0006] 3. dyno-proxy: Data storage proxy service of the existing framework. [0007] 4.Single Server DataStore: Homogeneous data storage service for single-point deployment. [0008] 5. Rack A / B: single-poi...

AI Technical Summary

Problems solved by technology

[0012] 1. The existing framework only supports isomorphic data synchronization of two mainstream NoSQL databases, and does not support heterogeneous data synchronization. The existing framework did not include heterogeneous data synchronization into the realization goal at the beginning of the design

[0013] 2. The existing framework does not support the function of fault data recovery. The existing framework is to solve the problem of high availability of single-point data storage. Fault recovery is not included in the implementation list as a core function

At present, it is only possible to manually copy data from other nodes to the faulty node to restore data. The recovery methods of each data storage are different, which shows the complexity of data recovery.

[0014] 3. The existing framework only supports deployment on Linux / Unix operating systems, and the cross-platform is slightly weaker

All build scripts of the framework use shell commands, which restricts them from building and compiling on the windows platform
