prefect-airbyte 0.3.2

prefect-airbyte contains tasks for interacting with Airbyte instances

prefect-airbyte

Welcome!

prefect-airbyte is a collection of prebuilt Prefect tasks and flows that can be used to quickly construct Prefect flows to interact with Airbyte.

Getting Started

Python setup

Requires an installation of Python 3.7+

We recommend using a Python virtual environment manager such as pipenv, conda or virtualenv.

These tasks are designed to work with Prefect 2.0. For more information about how to use Prefect, please refer to the Prefect documentation.

Airbyte setup

See the airbyte documention on how to get your own instance.

Installation

Install prefect-airbyte

pip install prefect-airbyte

A list of available blocks in prefect-airbyte and their setup instructions can be found here.

Examples

Create an AirbyteServer block and save it

from prefect_airbyte.server import AirbyteServer

# running airbyte locally at http://localhost:8000 with default auth
local_airbyte_server = AirbyteServer()

# running airbyte remotely at http://<someIP>:<somePort> as user `Marvin`
remote_airbyte_server = AirbyteServer(
    username="Marvin",
    password="DontPanic42",
    server_host="42.42.42.42",
    server_port="4242"
)

local_airbyte_server.save("my-local-airbyte-server")

remote_airbyte_server.save("my-remote-airbyte-server")

Trigger a defined connection sync

from prefect import flow
from prefect_airbyte.server import AirbyteServer
from prefect_airbyte.connections import AirbyteConnection
from prefect_airbyte.flows import run_connection_sync

server = AirbyteServer(server_host="localhost", server_port=8000)

connection = AirbyteConnection(
    airbyte_server=server,
    connection_id="e1b2078f-882a-4f50-9942-cfe34b2d825b",
    status_updates=True,
)

@flow
def airbyte_syncs():
    # do some setup

    sync_result = run_connection_sync(
        airbyte_connection=connection,
    )

    # do some other things, like trigger DBT based on number of records synced
    print(f'Number of Records Synced: {sync_result.records_synced}')

Export an Airbyte instance's configuration

NOTE: The API endpoint corresponding to this task is no longer supported by open-source Airbyte versions as of v0.40.7. Check out the Octavia CLI docs for more info.

import gzip

from prefect import flow, task
from prefect_airbyte.configuration import export_configuration
from prefect_airbyte.server import AirbyteServer

@task
def zip_and_write_somewhere(
      airbyte_config: bytearray,
      somewhere: str,
):
    with gzip.open(somewhere, 'wb') as f:
        f.write(airbyte_config)

@flow
def example_export_configuration_flow(filepath: str):

    # Run other tasks and subflows here

    airbyte_config = export_configuration(
        airbyte_server=AirbyteServer.load("my-airbyte-server-block")
    )

    zip_and_write_somewhere(
        somewhere=filepath,
        airbyte_config=airbyte_config
    )

if __name__ == "__main__":
    example_export_configuration_flow('*://**/my_destination.gz')

Use with_options to customize options on any existing task or flow

from prefect import flow
from prefect_airbyte.connections import AirbyteConnection
from prefect_airbyte.flows import run_connection_sync

custom_run_connection_sync = run_connection_sync.with_options(
    name="Custom Airbyte Sync Flow",
    retries=2,
    retry_delay_seconds=10,
)
 
 @flow
 def some_airbyte_flow():
    custom_run_connection_sync(
        airbyte_connection=AirbyteConnection.load("my-airbyte-connection-block")
    )
 
 some_airbyte_flow()
