A data exchange method and system

Abstract

The invention relates to a data exchange method and system. The method comprises the steps of building a first barrier between a data generation node to unlocked data bus read-in data and a data consumption node from unlocked data bus read data; building a second barrier between the data consumption node from the unlocked data bus read data and the data generation node to the unlocked data bus read-in data; monitoring whether the first barrier and the second barrier change or not; besides when the first barrier changes, making the data consumption node read the data, and when the second barrier changes, making the data generation node generate the data, wherein the data generation node, the first barrier, the data consumption node and the second barrier form circulation.

Description

technical field [0001] The present invention generally relates to the field of mobile service support, and more specifically relates to a data exchange method and system. Background technique [0002] At present, in the field of mobile service support systems, the concurrent data exchange among various service modules basically adopts read-write locks or compare and exchange (CAS) operations to perform concurrency control. Among the multiple business modules used for business data exchange, the data generation module first writes the business data to be exchanged into the storage medium for data exchange (such as files, databases, etc.), and then the data consumption module reads from the storage medium The media reads the data. When the same piece of data needs to be accessed by multiple data consumption modules, multiple copies of the data need to be made for different data consumption modules according to the number of consumption modules. After the consumption behavior...

Problems solved by technology

Due to the exclusiveness and exclusivity of write locks, the mutual exclusion of read locks and write locks, and the seriality of CAS operations, parallel operations will be converted into serial operations, which will cause a lot of overhead to the system and greatly limit the The concurrent performance of multiple business modules reading and writing the same business data based on the above data exchange mode restricts the business throughput of the business support system

In addition, for the same data, the practice of duplicating multiple copies according to the number of data consumers will not only increase the system response time due to data duplication, but also waste data storage space, resulting in increased hardware costs such as CPU resources and storage resources.
