Recover from accidental DynamoDB changes using Bulk Executor

This article explains how to use the Bulk Executor's revert-export command to recover from accidental DynamoDB changes by reverting specific writes captured in incremental exports.

• Revert targeted changes in-place without full table restoration, saving time and cost
• Use incremental exports with NEW_AND_OLD_IMAGES view type to capture original and modified states
• Apply transform functions to selectively undo changes, keep valid writes, or fix specific items
• Supports full reverts or selective reverts for migrations, batch jobs, and compliance scenarios
• Cost scales with change set size rather than full table size, making it efficient for large tables

The revert-export command provides a cost-effective alternative to point-in-time recovery for targeted data recovery scenarios.
