Data storage method and device, electronic equipment and computer readable storage medium

Abstract

The invention provides a data storage method and device, electronic equipment and a computer readable storage medium. The data storage method comprises the following steps: storing first data into a first data source; in response to receiving first indication information, storing second data to a second data source, wherein the first indication information indicates that the first data is successfully stored to the first data source. According to the embodiment of the invention, the second data is stored after the indication information indicating that the first data is successfully stored isreceived, so that the data can be ensured to be successfully stored.

Description

technical field [0001] The present disclosure relates to the field of information processing, and in particular to a data storage method, device, electronic equipment, and computer-readable storage medium. Background technique [0002] With the advancement of computer technology and the advent of the information age, users' demand for data storage is increasing rapidly. In the existing technology, in order to meet the requirements of processing speed and storage capacity, data is often stored through multiple data sources. When a computer device executes a business, the data modified or generated by executing the business may need to be stored in different data source. [0003] For example, the business performed by the computer equipment retrieves data a, data b, and data c from the first data source, the second data source, and the third data source respectively, and modifies data a, data b, and data c, as To maintain data consistency, the modified data a, data b, and da...

Problems solved by technology

[0003] For example, the business performed by the computer equipment retrieves data a, data b, and data c from the first data source, the second data source, and the third data source respectively, and modifies data a, data b, and data c, as To maintain data consistency, the modified data a, data b, and data c need to be written back to the data source. The conventional storage operation is to store data a, data b, and data c to the first data source respectively through write instructions. The second data source, and the third data source, but there will be the following technical problems: After the business performs the above conventional storage operations, it is impossible to determine whether the above data is correctly stored in the data source, for example, when the modified data b is stored The error cannot be successfully stored, and then the business or other business will use the wrong data b when calling data b, which will cause business errors
