Slipstream
Slipstream provides a data-flow model to simplify development of stateful streaming applications.
pip install slipstream-async
from asyncio import run
from slipstream import handle, stream
async def messages():
for emoji in '🏆📞🐟👌':
yield emoji
@handle(messages(), sink=[print])
def handle_message(msg):
yield f'Hello {msg}!'
if __name__ == '__main__':
run(stream())
Hello 🏆!
Hello 📞!
Hello 🐟!
Hello 👌!
Usage
Slipstream components interoperate with basic python building blocks:
Any-thing can be passed around as data- Any
Callablemay be used as a sink AsyncIterablesact as sources- Parallelize through
handle
A many-to-many relation is established by passing multiple sources / sinks.
Quickstart
Install Slipstream along with aiokafka (latest):
pip install slipstream-async[kafka]
Spin up a local Kafka broker with docker-compose.yml, using localhost:29091 to connect:
docker compose up broker -d
Copy-paste this snippet.
Features
slipstream.handle: bind streams (iterables) and sinks (callables) to user defined handler functionsslipstream.stream: start streamingslipstream.Topic: consume from (iterable), and produce to (callable) kafka using aiokafkaslipstream.Cache: store data to disk using rocksdictslipstream.Conf: set global kafka configuration (can be overridden per topic). Produce is fail-fast by default; setproduce_retries/produce_retry_backoffto retry retriable broker errors (sources pause viaConf.signal_iterableswhile retrying)slipstream.codecs.JsonCodec: serialize and deserialize json messagesslipstream.Checkpoint: recover from stream downtimes
