Abstract

The invention discloses a distributed architecture data consistency method based on a Zookeeper, and relates to the technical field of data processing. The method comprises the following steps of: initializing buffer data: loading data in a Zookeeper into a memory of each node after each node of the distributed system is started; defining a subscription monitoring method, each node subscribes to aZookeeper directory and data, deploying monitoring; and data synchronization: after monitoring the data change in the Zookeeper, updating the memory data of each node through a deployed monitoring method, and keeping the data synchronization among the nodes. According to the invention, a Zookeeper component is used as a cache data synchronization manager in a distributed architecture system; thedistributed multi-node cache data is synchronized in real time by utilizing a release and subscription mechanism of the Zookeeper, and meanwhile, the data access speed is greatly increased based on aZookeeper database of a memory, so that the performance and the data consistency are well improved in a distributed architecture system.

Description

technical field [0001] The invention belongs to the technical field of data processing, and in particular relates to a distributed architecture data consistency method based on Zookeeper. Background technique [0002] Zookeeper is an open source distributed application coordination service. Distributed applications can implement functions such as data publishing / subscribing, load balancing, distributed coordination / notification, cluster management, distributed locks and distributed queues based on Zookeeper. [0003] CAP theory in the distributed field: No distributed system can simultaneously meet the three basic requirements of Consistency, Availability, and Partition tolerance. In a distributed architecture, multi-node deployment is used to achieve high availability. Partition fault tolerance is the most basic requirement. How to balance consistency and availability is the main problem faced by the distributed architecture. Therefore, the BASE theory came into being. The...
