- Bypass redundant SourceItem validation by validating raw record new_image dict directly against DestinationItem. - Avoid SourceItem instantiation during REMOVE events by extracting item ID string directly from record.dynamodb.keys. - Enforce safety check to verify record.dynamodb is not None. - Use the standard .dump() helper method on the model instead of .model_dump().

This pull request implements an elegant, high-performance optimization in the DynamoDB Stream handler templates.
💡 What
new_imagedictionary directly againstDestinationIteminstead of double-validating first againstSourceItemand then converting. This reduces schema processing overhead.idstring directly fromrecord.dynamodb.keys, completely bypassingSourceItemmodel instantiation.record.dynamodbis notNonebefore referencing its attributes to avoid unexpected runtimeAttributeErrorfailures..dump()helper method inherited fromObjectfor consistent camelCase serialization.🎯 Why
DynamoDB Streams process large batches of data under tight execution time limits in AWS Lambda. Skipping redundant model instantiations and validations significantly decreases Lambda execution latency and memory usage.
📊 Impact
🔬 Measurement
All 71 tests in the suite successfully pass with zero regressions.
