Data sharing method, data sharing system, and computer-readable storage medium

Abstract

The invention discloses a data sharing method, a data sharing system and a computer readable storage medium. The method comprises: a data consumer is associated with a key of the data sent to obtain afirst association relationship; a data consumer is associated with a key of the requested data to obtain a second association relationship; When receiving the data sent by the data producer, if the key in a second association is the same as the key of the data, the data is sent to the data consumer in the second association; and if the key is the same as the key of the data, the data is sent to the data consumer in the second association. When a request sent by a data consumer is received, if a key in a first association relationship is the same as the key of the requested data, data corresponding to the key in the first association relationship is sent to the data consumer. The invention is not only simpler to use, but also greatly reduces the coupling degree of the system, the change notification mechanism also avoids the performance consumption caused by frequent query data change, and at the same time, the data sharing across machines and networks can be easily realized.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a data sharing method, a data sharing system and a computer-readable storage medium. Background technique [0002] In modern application systems, especially in complex application groups with multiple servers, there are a large number of shared data requirements among multiple applications / services, such as some common parameter configurations, etc.; how to flexibly share multiple applications / services It becomes a topic worth studying to share these data among them, and when the data changes, all ends can get timely notification. [0003] At present, there are two conventional methods for sharing data between multiple applications. One is to use memory sharing to write the required data into the shared memory, and the demander who needs the data reads the data from the shared memory. ; The disadvantage of this approach is obvious, it can only be limited to the local machine for d...

[0003] At present, there are two conventional methods for sharing data between multiple applications. One is to use memory sharing to write the required data into the shared memory, and the demander who needs the data reads the data from the shared memory. ;The disadvantage of this approach is obvious, it can only be limited to the local machine for data sharing, and because of this sharing method, multiple applications / services increase the coupling degree, and it still cannot solve the demand for real-time notification of changes

Another conventional method is to use files or DBMS as the medium to write the data that needs to be shared, and to query regularly when needed by the demander to obtain the latest shared data; although this method effectively reduces the degree of coupling, it can also Solve the problem of cross-machine data sharing, but there are still problems that changes cannot be notified, frequent queries require high consumption, and calls are not intuitive
