Microservice Configuration via Active Cluster Pulling

The patent inverts the traditional data distribution model by switching from passive pushing (main cluster pushes to all service clusters) to active pulling (service clusters actively acquire from main cluster). This inversion resolves the technical contradiction by transferring the initiative of data acquisition to service clusters, thereby reducing the load on the main cluster while ensuring all service clusters obtain necessary configuration and service data.

The patent applies the inversion principle by reversing the data distribution direction from push-based to pull-based. Service clusters actively acquire configuration and service data from the main cluster when needed, rather than receiving continuous pushes. This approach maintains data distribution efficiency while eliminating the main cluster's role as an active pusher, thereby reducing its load and preventing it from becoming a single point of failure.

The patent implements periodic action by having service clusters send acquisition requests to the main cluster at specific intervals or when data changes are detected, rather than continuously polling. This periodic acquisition mechanism ensures data freshness is maintained while significantly reducing network load and the burden on the main cluster compared to continuous polling approaches.
