Connecting Lambda To Dynamodb

This handles the full setup for connecting Lambda to DynamoDB, including IAM execution roles, stream configuration, and event source mapping. You'd use this when building event-driven architectures where Lambda needs to react to table changes or just read/write data. The skill includes a specific connection procedure and covers the usual gotchas like permission denied errors, inactive event source mappings, and timeout issues from incorrect batch sizes. It's focused on the infrastructure wiring rather than application logic, so if you already know what policies and stream settings you need, this should get everything connected properly without hunting through AWS docs.
