Control Node Authority Update Notification for Distributed Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In distributed storage systems, updating authority information is cumbersome and inefficient, leading to potential inconsistencies due to machine failures and network anomalies.
Innovation Solution
A method where a control node acquires updated authority information and transmits a first update notification to a data node, allowing the data node to directly update based on the included information, thereby simplifying the updating process and improving efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the traditional updating process is used, then the authority information can be updated, but the updating process is cumbersome and the updating efficiency is low
Solution Approach 1:
The patent combines the update notification and the updated authority information into a single message packet. The control node packs both the notification to update and the actual updated authority information together, eliminating the need for separate transmission steps and reducing the complexity of the updating process while improving efficiency
Solution Approach 2:
The control node performs preliminary action by acquiring and packing the updated authority information before transmitting it to the data node. This ensures that the data node receives ready-to-use updated information without needing to perform additional acquisition steps, thereby simplifying the overall process and improving updating efficiency
2Reliability
If the traditional updating process is used, then the authority information can be updated, but the risk of inconsistency due to machine failures and network anomalies is high
Solution Approach 1:
The patent implements a feedback mechanism where the data node sends an acknowledgment back to the control node after successfully updating the authority information. The control node waits for this feedback to confirm successful update, ensuring consistency even in case of network anomalies or machine failures, while the overall process remains efficient due to the combined notification and information transmission
Data Source
AI summary
The present disclosure provides an updating method, a terminal and an electronic device. The updating method may include: acquiring updated authority information; and transmitting a first update notification to a first data node, the first update notification comprising the updated authority information. When a control node transmits the first update notification to the first data node, such notification includes the updated authority information.
