Firehose

Firehose is a cloud native service for delivering real-time streaming data to destinations such as service endpoints (HTTP or GRPC) & managed databases (Postgres, InfluxDB, Redis, Elasticsearch, Prometheus and MongoDB). With Firehose, you don't need to write applications or manage resources. It can be scaled up to match the throughput of your data. If your data is present in Kafka, Firehose delivers it to the destination(SINK) that you specified.

Key Features

Discover why users choose Firehose as their main Kafka Consumer

• Sinks: Firehose supports sinking stream data to :

  • log console
  • MongoDB
  • Prometheus
  • HTTP
  • GRPC
  • PostgresDB(JDBC)
  • InfluxDB
  • Elasticsearch
  • Redis
  • Bigquery
  • BigTable
  • Blob Storage/Object Storage :
    • Google Cloud Storage

• Scale: Firehose scales in an instant, both vertically and horizontally for high performance streaming sink and zero data drops.

• Extensibility: Add your own sink to firehose with a clearly defined interface or choose from already provided ones.

• Runtime: Firehose can run inside VMs or containers in a fully managed runtime environment like kubernetes.

• Metrics: Always know what’s going on with your deployment with built-in monitoring of throughput, response times, errors and more.

Usage

Explore the following resources to get started with Firehose:

• Guides provides guidance on creating Firehose with different sinks.
• Concepts describes all important Firehose concepts.
• Reference contains details about configurations, metrics and other aspects of Firehose.
• Contribute contains resources for anyone who wants to contribute to Firehose.

Run with Docker

Use the docker hub to download firehose docker image. You need to have docker installed in your system.

# Download docker image from docker hub
$ docker pull raystack/firehose

# Run the following docker command for a simple log sink.
$ docker run -e SOURCE_KAFKA_BROKERS=127.0.0.1:6667 -e SOURCE_KAFKA_CONSUMER_GROUP_ID=kafka-consumer-group-id -e SOURCE_KAFKA_TOPIC=sample-topic -e SINK_TYPE=log -e SOURCE_KAFKA_CONSUMER_CONFIG_AUTO_OFFSET_RESET=latest -e INPUT_SCHEMA_PROTO_CLASS=com.github.firehose.sampleLogProto.SampleLogMessage -e SCHEMA_REGISTRY_STENCIL_ENABLE=true -e SCHEMA_REGISTRY_STENCIL_URLS=http://localhost:9000/artifactory/proto-descriptors/latest/raystack/firehose:latest

Note: Make sure your protos (.jar file) are located in work-dir, this is required for Filter functionality to work.

Run with Kubernetes

• Create a firehose deployment using the helm chart available here
• Deployment also includes telegraf container which pushes stats metrics
