Pull Controller Timestamp Logic for Data Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Business systems integrated across different vendors and computing platforms often face compatibility issues, particularly in data synchronization, where systems without push notification support may not receive updated data, leading to inaccurate copies and versioning problems.
Innovation Solution
A pull mechanism is implemented using a pull controller that sends pull requests with timestamps and selection criteria to ensure all updated data is retrieved from the sender system, even if it doesn't support push notifications, and includes error monitoring and tracking to guarantee data integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pull mechanism is implemented to retrieve updated data from the sender system, then data synchronization reliability is improved, but system complexity increases due to the need to track pull requests, manage timestamps, and handle selection criteria
Solution Approach 1:
The receiver system implements feedback mechanisms by tracking pull request status, timestamps, and selection criteria to ensure reliable data synchronization. The system monitors whether pull requests were successful and uses this feedback to determine when to retry or when data is fully synchronized, resolving the contradiction between reliability and complexity through structured feedback loops.
Solution Approach 2:
The system performs preliminary actions by pre-configuring pull request parameters, timestamps, and selection criteria before actual data retrieval. This allows the system to maintain synchronization reliability through prepared request templates while reducing runtime complexity by avoiding ad-hoc configuration during data pull operations.
2Reliability
If the receiver system continuously monitors for data updates, then data integrity is improved, but processing time and resource consumption increase
Solution Approach 1:
Instead of continuous monitoring, the system uses periodic pull requests triggered by timestamps and update indicators. The receiver system checks for updates at scheduled intervals or when specific events occur, maintaining data integrity through regular synchronization while reducing processing time by avoiding constant monitoring and only acting when changes are detected.
Solution Approach 2:
The sender system performs self-service by automatically notifying the receiver system when data updates occur through push notifications or update indicators. This eliminates the need for the receiver to continuously poll for changes, maintaining data integrity through automatic updates while significantly reducing processing time and resource consumption.
3Adaptability or versatility
If the system supports both restricted and unrestricted pull requests, then adaptability is improved, but the complexity of managing different pull request types increases
Solution Approach 1:
The system implements dynamic pull request handling by allowing the receiver to adaptively select between restricted and unrestricted pull request types based on current synchronization needs. The system dynamically adjusts pull request parameters, selection criteria, and scope according to the synchronization state and requirements, providing flexibility while managing complexity through conditional logic and state-aware decision making.
Data Source
AI summary
Methods and apparatus, including computer program products, are provided for data pulls. In some implementations, a method may be provided which includes accessing an object to determine whether a prior pull request is at least one of an a restricted type or an unrestricted type; generating, when the prior pull request is determined to be of the unrestricted type and successful, a pull request including a time stamp obtained from the object; generating, when the prior pull request is determined to be at least one of the restricted type or unsuccessful, a pull request including at least one of a selection criteria and another time stamp obtained from the object, the other time stamp representing a prior successful pull request; sending, by a first processor, the generated pull request to a second processor having master data to obtain an update to data at the first processor.
