Problems solved by technology

However, when performing disaster backup between different regions, asynchronous data backup through storage applications is still used. Due to the network delay across regions, some data will still be lost during disaster recovery.

Embodiment Construction

[0025] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0026] When talking about the cross-regional data synchronization mechanism under the remote multi-active architecture, we need to look at it from the following dimensions

[0027] Timeliness: The timeliness of cross-regional data synchronization mainly requires that within a certain distance and a certain effective bandwidth, the same amount of data, the shorter the synchronization time, the better, and real-time synchronization can be achieved as much as possible.

[0028] Guarantee degree: that is, the degree of guarantee of data consistency. In fact, there is no absolute 100% consistency, especially in different regions, so the difference between different mechan...

Abstract

The invention relates to a transaction data recording method and a transaction data playback method. The recording method comprises the following steps: a front-end system sends a transaction requestto an ESC cloud terminal, asynchronously writes the transaction request into a local kafka cluster, and synchronizes the transaction request to a remote data center through a MirorMaker mirror image;if the local transaction recording compensation application successfully receives the ACK message, verifying the transaction record according to the ACK message; the local ESC cloud terminal asynchronously writes a response message into the local kafka cluster after receiving the response of the back-end service system, and creates a top-to-end service system; the top-to-top is sent to the server,and the top-to-top is sent to the server. Persistence is carried out on the res message to a local database, and the top-value-is obtained through the MirorMaker mirror image. And the res message issynchronized to a remote data center. According to the transaction data recording method and the transaction data playback method, the data difference of asynchronous data synchronization is made up,and the final consistency of the data can be guaranteed when remote fault switching is carried out.

Description

technical field [0001] The invention relates to the technical field of cloud computing, in particular to a method for recording and synchronizing transaction data and a method for replaying transaction data. Background technique [0002] In the past 10 years, the People's Bank of China and the China Banking Regulatory Commission have issued a number of documents to guide and standardize the disaster recovery construction of data centers. Taking the "Commercial Bank Data Center Supervision Guidelines" issued by the China Banking Regulatory Commission as an example, it clearly requires that "commercial banks should obtain financial Establish a production center within two years of the license", "Set up a disaster recovery center within two years after the establishment of the production center", etc. At present, state-owned holding banks, joint-stock banks and most city commercial banks have already carried out the construction of data centers in two places and three centers w...
