⚡ Bolt: optimize DynamoDB Stream hot path#87
Conversation
…dation This commit improves the performance of the DynamoDB Stream handler by: 1. Removing the redundant `SourceItem` model instantiation and validation for `INSERT` and `MODIFY` events. 2. Validating the record dictionary directly against the `DestinationItem` model. 3. Bypassing model instantiation entirely for `REMOVE` events by accessing the primary key directly from the record keys. These changes reduce CPU overhead and latency in the stream processing hot path. Applications at scale will see measurable improvements in execution time and resource consumption. Journaled in .jules/bolt.md.

Optimized the DynamoDB Stream handler by removing redundant Pydantic validation steps. For INSERT/MODIFY events, the code now validates directly into the destination model instead of through an intermediate source model. For REMOVE events, it bypasses model instantiation entirely by using direct dictionary access for the primary key.
