Filter, transform, and load your DynamoDB table exports using AWS Glue

This article explains how to load DynamoDB table exports into destination tables using AWS Glue with advanced control and transformation capabilities.

• Load full or incremental DynamoDB exports with precise control over write rates
• Use optional transform functions to filter, modify, or fan-out items during load
• Bulk Executor open-source tool provides the load-export command for this functionality
• Supports isolated table synchronization and data transformation use cases
• AWS Glue handles parallelization across workers with distributed rate-limiting
• Validates exports before loading and detects full vs. incremental formats automatically
• Verify data integrity post-load using the bulk diff tool
• Example: 100M items loaded in 12 minutes at ~$69.50 DynamoDB + ~$10 Glue cost

This technique enables large-scale DynamoDB migrations and synchronizations with granular control over data transformation and loading rates.
