what is the appropriate return value for the write method in a python destination connector

The

write

operation in a Python destination connector doesn't explicitly return a value. Instead, it performs two main tasks: 1. It writes data to the underlying destination. 2. It outputs `AirbyteMessage`s of type

AirbyteStateMessage

to stdout. These messages indicate which records have been written so far during a sync. This is important to avoid re-extracting messages from the source. Here's an example of how you might implement the

write

method in your

destination.py

file:

python def write(config: Mapping[str, Any], configured_catalog: ConfiguredAirbyteCatalog, input_messages: Iterable[AirbyteMessage]) -> Iterable[AirbyteMessage]:     ...

In this function,

config

is the configuration file used to run the connector,

configured_catalog

describes the schema of the incoming data and how it should be written to the destination, and

input_messages

are the records to be written to the destination. For more information, you can refer to the [Airbyte Protocol documentation](https://docs.airbyte.com/understanding-airbyte/airbyte-protocol#write) and the [Python destination connector development tutorial](https://docs.airbyte.com/connector-development/tutorials/building-a-python-destination).
