Synchronization Service Checkpoint Caching Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The frequent polling of service provider networks by multiple computing devices for synchronization leads to significant consumption of computing resources, with many queries resulting in no changes, thus wasting resources and increasing load.
Innovation Solution
Implementing a synchronization service that caches the oldest checkpoint with no changes, allowing devices to skip queries by providing updated checkpoints and metadata, reducing unnecessary queries to the storage service.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If computing devices frequently poll the service provider network for content synchronization, then the content remains up to date across all devices, but computing resources are significantly consumed
Solution Approach 1:
The system performs preliminary actions by generating and caching checkpoints that record the state of content at specific times. These checkpoints are prepared in advance and stored for later comparison, allowing the system to determine whether content has changed without performing full content comparisons during each polling cycle.
Solution Approach 2:
The system creates copies of content state information in the form of checkpoints and caches them. Instead of repeatedly accessing and comparing actual content data, the system works with these lightweight copies (checkpoints) that represent the content state at different points in time, significantly reducing the computational overhead of synchronization operations.
2Speed
If computing devices poll the service provider network every 15 seconds to remain synchronized, then content updates are detected quickly, but the aggregate of queries consumes significant computing resources
Solution Approach 1:
The system extracts only the essential synchronization information needed to determine whether content has changed. Instead of transferring or comparing full content data during each polling cycle, the system extracts and compares lightweight checkpoint data that indicates content state, minimizing network traffic and computational resources while maintaining synchronization speed.
3Adaptability or versatility
If the service provider network processes queries from millions of users, then all users can access and synchronize their content, but the network infrastructure requires significant computing resources
Solution Approach 1:
The system creates and distributes lightweight checkpoint copies to multiple client devices, allowing them to perform local comparisons without requiring server-side content comparison operations. This approach enables millions of users to synchronize their content while the server infrastructure processes only small checkpoint data structures rather than large content files.
4Reliability
If computing devices send queries to check for content changes, then synchronization is maintained, but approximately half of the queries indicate no changes have occurred, wasting resources
Solution Approach 1:
The system performs preliminary actions by pre-generating and caching checkpoints that document content state at specific times. When a synchronization query occurs, the system compares the current checkpoint against the cached checkpoint to immediately determine whether content has changed, avoiding unnecessary full content retrievals and processing for queries where no changes have occurred.
Data Source
AI summary
A service provider network includes a host computer that communicates with a plurality of client devices associated with a user. In order to synchronize the plurality of client devices with respect to content stored within the service provider network, a synchronization service checks to determine if a checkpoint is present within the synchronization service when a request for updated content is received from one of the client devices. If no checkpoint is present in the synchronization service, then content within the user's account may have been updated. If a checkpoint is stored within the synchronization service, then the checkpoint in the synchronization service is compared with a checkpoint in the request. If the checkpoint in the synchronization service is older, content in the user's account has not been updated. If the checkpoint in the request is older, then content in the user's account may have been updated.
