Problems solved by technology

[0008] Online synchronization is mainly divided into two categories, one uses a private protocol for synchronization, which cannot be applied to other types of databases, and its versatility is not strong
Generally speaking, this method of synchronization adopts full-copy synchronization, that is, it is aimed at the entire library or the entire table as the granularity, and cannot be specific to the relevant fields of a specific table.
[0009] Another online mode, the data collection end and the data import end are integrated in one program, and the entire data is transferred within the program. Although the exchange of data between processes is avoided, the flexibility is low, and the development technology has limitations. Requires a unified technology stack for all implementations
At the same time, the integrated architecture determines this mode, which cannot take into account both data sources and data purposes. In some application scenarios, the application is limited

Embodiment Construction

[0049] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present invention, not all Embodiments, based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0050] The whole data is abstracted into three modules, which serve as the Reader at the data collection end, that is, the producer that obtains information from the original data source. As the Transfer of message delivery, that is, the deliverer responsible for the intermediate message,

[0051] And the Writer as the final consumer of the message, that is, the writer of the target library that performs data conversion proce...

Abstract

The invention provides a CMSP-based DRDB database data synchronization method, belongs to the technical field of database synchronization, and aims to realize synchronization of database meta-information and record messages from other databases to a DRBD by abstracting related logic components, separating responsibilities and defining message formats and models. The throughput of total synchronization and the effectiveness of incremental synchronization are both considered under the condition of relatively small sacrifice.

Description

technical field [0001] The invention relates to technologies such as automatic mapping of heterogeneous database data types, type conversion, message construction and distribution synchronization method, agreement between components, etc., and particularly relates to a CMSP-based DRDB database data synchronization method. Background technique [0002] Now the main means of database synchronization include offline synchronization and online synchronization. Offline synchronization mainly adopts the method of persisting as intermediate files, which has the characteristics of large throughput and strong versatility; online synchronization generally uses private protocols between the same database to achieve master-backup, master-slave copy and other schemes, and has real-time performance Strong, high performance advantages. But both also have their corresponding defects more or less. [0003] offline sync [0004] Data needs to be periodically persisted as intermediate files...
