Benthos alternatives and similar packages
Based on the "Messaging" category
Do you think we are missing an alternative of Benthos or a related project?
Benthos is a high performance and resilient stream processor, able to connect various sources and sinks in a range of brokering patterns and perform hydration, enrichments, transformations and filters on payloads.
Stream pipelines are defined in a single config file, allowing you to declare connectors and a list of processing stages:
input: gcp_pubsub: project: foo subscription: bar pipeline: processors: - bloblang: | root.message = this root.meta.link_count = this.links.length() root.user.age = this.user.age.number() output: redis_streams: url: tcp://TODO:6379 stream: baz max_in_flight: 20
Yep, we got 'em. Benthos implements transaction based resiliency with back pressure. When connecting to at-least-once sources and sinks it guarantees at-least-once delivery without needing to persist messages during transit.
Supported Sources & Sinks
AWS (DynamoDB, Kinesis, S3, SQS, SNS), Azure (Blob storage, Table storage, output only), Elasticsearch (output only), File, GCP (pub/sub), HDFS, HTTP (server and client, including websockets), Kafka, Memcached (output only), MQTT, Nanomsg, NATS, NATS Streaming, NSQ, AMQP 0.91 (RabbitMQ), AMQP 1, Redis (streams, list, pubsub, hashes), SQL (MySQL, PostgreSQL, Clickhouse), Stdin/Stdout, TCP & UDP, sockets and ZMQ4.
Connectors are being added constantly, if something you want is missing then open an issue.
If you want to dive fully into Benthos then don't waste your time in this dump, check out the documentation site.
For guidance on how to configure more advanced stream processing concepts such as stream joins, enrichment workflows, etc, check out the cookbooks section.
For guidance on building your own custom plugins check out this example repo.
Grab a binary for your OS from here. Or use this script:
curl -Lsf https://sh.benthos.dev | bash
Or pull the docker image:
docker pull jeffail/benthos
Benthos can also be installed via Homebrew:
brew install benthos
For more information check out the getting started guide.
benthos -c ./config.yaml
Or, with docker:
# Send HTTP /POST data to Kafka: docker run --rm \ -e "INPUT_TYPE=http_server" \ -e "OUTPUT_TYPE=kafka" \ -e "OUTPUT_KAFKA_ADDRESSES=kafka-server:9092" \ -e "OUTPUT_KAFKA_TOPIC=benthos_topic" \ -p 4195:4195 \ jeffail/benthos # Using your own config file: docker run --rm -v /path/to/your/config.yaml:/benthos.yaml jeffail/benthos
Benthos serves two HTTP endpoints for health checks:
/pingcan be used as a liveness probe as it always returns a 200.
/readycan be used as a readiness probe as it serves a 200 only when both the input and output are connected, otherwise a 503 is returned.
Benthos exposes lots of metrics either to Statsd, Prometheus or for debugging purposes an HTTP endpoint that returns a JSON formatted object. The target can be specified [via config][metrics-config].
Benthos provides lots of tools for making configuration discovery, debugging and organisation easy. You can read about them here.
It is possible to select fields inside a configuration file to be set via environment variables. The docker image, for example, is built with [a config file][env-config] where all common fields can be set this way.
Build with Go (1.11 or later):
git clone firstname.lastname@example.org:Jeffail/benthos cd benthos make
It's pretty easy to write your own custom plugins for Benthos, take a look at this repo for examples and build instructions.
There's a multi-stage
Dockerfile for creating a Benthos docker image which
results in a minimal image from scratch. You can build it with:
Then use the image:
docker run --rm \ -v /path/to/your/benthos.yaml:/config.yaml \ -v /tmp/data:/data \ -p 4195:4195 \ benthos -c /config.yaml
There are a [few examples here][compose-examples] that show you some ways of
setting up Benthos containers using
Benthos supports ZMQ4 for both data input and output. To add this you need to install libzmq4 and use the compile time flag when building Benthos:
Or to build a docker image using CGO, which includes ZMQ:
