Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If data is synchronized frequently to ensure timeliness, then data freshness is improved, but system resource consumption and complexity increase
Solution Approach 1:
The system performs preliminary actions by creating checkpoints before data synchronization and updating metadata in advance. The synchronization server pre-processes data transformations and prepares update packages before actual synchronization occurs, reducing the complexity of real-time synchronization operations.
Solution Approach 2:
The system implements feedback mechanisms through notifications sent to downstream applications when data synchronization is complete or failed. This feedback loop allows the system to adjust synchronization frequency and resources based on actual data freshness requirements and system state, optimizing the balance between timeliness and complexity.
2Measurement precision
If data is updated in real-time to maintain accuracy, then data accuracy is improved, but system performance and reliability deteriorate due to network issues and large dataset size
Solution Approach 1:
The system applies beforehand cushioning by creating checkpoints before data updates and implementing error handling mechanisms. If synchronization fails or data accuracy cannot be verified, the system can rollback to the checkpoint state, ensuring system reliability is maintained even when real-time updates encounter network issues or other failures.
Solution Approach 2:
The synchronization server acts as an intermediary between the source database and downstream applications. It buffers data transformations, manages update queues, and handles errors independently, preventing direct failures from propagating and maintaining system reliability while still achieving data accuracy through controlled update processes.
3Loss of information
If tolerance levels are set low to ensure data completeness, then data completeness is improved, but update frequency and productivity decrease
Solution Approach 1:
The system applies local quality by setting different tolerance levels for different data tables based on their specific requirements. Critical data tables with high completeness requirements can have low tolerance levels, while less critical tables can have higher tolerance levels, allowing the system to maintain data completeness where needed while preserving overall update frequency and productivity.
Data Source
AI summary
Computer-implemented systems and methods for synchronizing data for dataset execution. The system includes a source database that stores a canonical dataset, a secondary database that stores a processed dataset, and a synchronization server that comprises a processor and a memory. The processor is configured to monitor for a publication of one or more source tables and when the publication is detected, identify the processed tables, corresponding to the source tables, to be updated in the processed dataset. The processor determines a tolerance level corresponding to each processed table and updates the processed tables in the processed dataset. The tolerance level can be based on an execution requirement of a downstream application. In some embodiments, the downstream application can be a machine learning model. The processor determines whether the processed tables in the processed dataset were successfully updated within the tolerance levels and transmits a notification based on the determination.
