Automated Reference Data Synchronization with Azure Databricks Delta Tables

Problem Statement: Currently, synchronizing Reference Data with Azure Databricks Delta Tables is a manual process involving data export from IKC and manual transfer to the Azure cloud platform. This approach is inefficient and error-prone.

Proposed Solution: Implement an automated data synchronization function that can handle both incremental and full data syncs between Reference Data and Azure Databricks Delta Tables. Function can be invoked via UI or via API for Data sync-up.

Function Requirements:

• Incremental Data Sync:

  • CDC Tracking: Utilize Change Data Capture (CDC) mechanisms to track changes in Reference Data.

  • Delta Load: Identify delta changes and efficiently load them into Azure Databricks Delta Tables.

  • Checkpoint Management: Maintain a checkpoint to ensure that only new or modified data is synchronized.

• Full Data Sync:

  • Data Extraction: Extract the entire Reference Data dataset.

  • Data Loading: Load the extracted data into Azure Databricks Delta Tables, potentially optimizing the loading process for large datasets.

• Error Handling: Implement robust error handling mechanisms to prevent data loss or corruption during the synchronization process.

• Security: Ensure data security and access controls during the synchronization process.

• Azure Databricks Integration: Leverage Azure Databricks APIs and connectors to interact with Delta Tables efficiently.

Benefits of Automation:

• Efficiency: Reduce manual effort and time spent on data synchronization.

• Accuracy: Minimize the risk of errors during data transfer and updates.

• Consistency: Ensure consistent data synchronization, reducing the likelihood of inconsistencies between Reference Data and Azure Databricks Delta Tables.

• Scalability: Handle synchronization for large datasets and complex scenarios.

• Real-time Updates: Enable near real-time data updates in Azure Databricks Delta Tables based on changes in Reference Data.
