# BulkSink
|
|
**BulkSink** is an optional component in the workflow. It can be used to bulk update the records generated in a workflow. It needs to be used in conjunction with Stage
|
|
|
|
## API
|
|
|
|
```python
|
|
@dataclass # type: ignore[misc]
|
|
class BulkSink(Closeable, metaclass=ABCMeta):
|
|
ctx: WorkflowContext
|
|
|
|
@classmethod
|
|
@abstractmethod
|
|
def create(cls, config_dict: dict, metadata_config_dict: dict, ctx: WorkflowContext) -> "BulkSink":
|
|
pass
|
|
|
|
@abstractmethod
|
|
def write_records(self) -> None:
|
|
pass
|
|
|
|
@abstractmethod
|
|
def get_status(self) -> BulkSinkStatus:
|
|
pass
|
|
|
|
@abstractmethod
|
|
def close(self) -> None:
|
|
pass
|
|
```
|
|
|
|
**create** method is called during the workflow instantiation and creates an instance of the bulk sink.
|
|
|
|
**write_records** this method is called only once in Workflow. Its developer responsibility is to make bulk actions inside this method. Such as read the entire file or store to generate the API calls to external services.
|
|
|
|
**get_status** to report the status of the bulk_sink ex: how many records, failures or warnings etc.
|
|
|
|
**close** gets called before the workflow stops. Can be used to clean up any connections or other resources.
|
