Adds the standard deferrable path to `DynamoDBValueSensor`, which currently only supports poke/reschedule modes and holds a worker slot while waiting. - `deferrable` param (default from `operators.default_deferrable`, per provider convention); `execute()` defers to a new `DynamoDBValueSensorTrigger`, `execute_complete()` validates the trigger event. - The trigger polls the item asynchronously. `DynamoDBHook` is resource-based but aiobotocore only exposes clients, so the trigger uses a client-type `AwsBaseHook` with low-level `get_item` and deserializes the attribute via boto3's `TypeDeserializer` — semantics identical to the sync `poke()` (ClientError tolerated, single value or iterable matched). This mirrors how `EC2StateSensorTrigger` handles the same client/resource split. - Trigger registered in `provider.yaml` / `get_provider_info.py`; docs note added; unit tests for sensor deferral and trigger (serialization + async run paths). The issue proposes DynamoDB Streams + SQS; I went with the async-polling trigger instead since it is the established pattern for the provider's deferrable sensors and requires no extra AWS infrastructure — happy to discuss if maintainers prefer the Streams-based design. closes: #69051 --- ##### Was generative AI tooling used to co-author this PR? - [X] Yes (Claude Code) Generated-by: Claude Code following [the guidelines](https://github.com/apache/airflow/blob/main/contributing-docs/05_pull_requests.rst#gen-ai-assisted-contributions) --- * Read the **[Pull Request Guidelines](https://github.com/apache/airflow/blob/main/contributing-docs/05_pull_requests.rst#pull-request-guidelines)** for more information.
