README
Broadway
Build concurrent and multi-stage data ingestion and data processing pipelines with Elixir. Broadway allows developers to consume data efficiently from different sources, known as producers, such as Amazon SQS, Apache Kafka, Google Cloud PubSub, RabbitMQ, and others. Broadway pipelines are concurrent and robust, thanks to the Erlang VM and its actors.
Broadway takes its name from the famous Broadway street in New York City, renowned for its stages, actors, and producers.
To learn more and get started, check out our official website and our guides and docs.
Built-in features
Broadway takes the burden of defining concurrent GenStage topologies and provide a simple configuration API that automatically defines concurrent producers, concurrent processing, batch handling, and more, leading to both time and cost efficient ingestion and processing of data. It features:
- Back-pressure
- Automatic acknowledgements at the end of the pipeline
- Batching
- Fault tolerance
- Graceful shutdown
- Built-in testing
- Custom failure handling
- Ordering and partitioning
- Rate-limiting
- Metrics
Producers
There are several producers that you can use to integrate with existing services and technologies. See the docs for detailed how-tos and supported producers.
Installation
Add :broadway
to the list of dependencies in mix.exs
:
def deps do
[
{:broadway, "~> 1.0"}
]
end
A quick example: SQS integration
Assuming you have added broadway_sqs
as a dependency and configured your SQS credentials accordingly, you can consume Amazon SQS events in only 20 LOCs:
defmodule MyBroadway do
use Broadway
alias Broadway.Message
def start_link(_opts) do
Broadway.start_link(__MODULE__,
name: __MODULE__,
producer: [
module: {BroadwaySQS.Producer, queue_url: "https://us-east-2.queue.amazonaws.com/100000000001/my_queue"}
],
processors: [
default: [concurrency: 50]
],
batchers: [
s3: [concurrency: 5, batch_size: 10, batch_timeout: 1000]
]
)
end
def handle_message(_processor_name, message, _context) do
message
|> Message.update_data(&process_data/1)
|> Message.put_batcher(:s3)
end
def handle_batch(:s3, messages, _batch_info, _context) do
# Send batch of messages to S3
end
defp process_data(data) do
# Do some calculations, generate a JSON representation, process images.
end
end
Once your Broadway module is defined, you just need to add it as a child of your application supervision tree as {MyBroadway, []}
.
Comparison to Flow
You may also be interested in Flow by Dashbit. Both Broadway and Flow are built on top of GenStage. Flow is a more general abstraction than Broadway that focuses on data as a whole, providing features like aggregation, joins, windows, etc. Broadway focuses on events and on operational features, such as metrics, automatic acknowledgements, failure handling, and so on.
