GearPump is a lightweight real-time big data streaming engine. It is inspired by recent advances in the Akka framework and a desire to improve on existing streaming frameworks.

The name GearPump is a reference to the engineering term “gear pump,” which is a super simple pump that consists of only two gears, but is very powerful at streaming water.

We model streaming within the Akka actor hierarchy.

Per initial benchmarks we are able to process 11 million messages/second (100 bytes per message) with a 17ms latency on a 4-node cluster.

For steps to reproduce the performance test, please check Performance benchmark

There is a 20 pages technical paper on typesafe blog, with technical highlights https://typesafe.com/blog/gearpump-real-time-streaming-engine-using-akka

Check Introduction

Check guide Get Started

1). Clone the GearPump repository

  git clone https://github.com/gearpump/gearpump.git
  cd gearpump

2). Build package

  ## Please use scala 2.11 or 2.10
  ## The target package path: target/gearpump-$VERSION.tar.gz
  sbt clean +assembly +packArchiveZip ## Or use: sbt clean assembly pack-archive

After the build, there will be a package file gearpump-${version}.tar.gz generated under target/ folder.

To build scala document, use

   ## Will generate the scala doc under target/scala_2.xx/unidoc/
   sbt unidoc

NOTE: The build requires network connection. If you are behind an enterprise proxy, make sure you have set the proxy in your env before running the build commands. For windows:

Set HTTP_PROXY=http://host:port
set HTTPS_PROXT= http://host:port

For Linux:

export HTTP_PROXY=http://host:port
export HTTPS_PROXT= http://host:port

After the build, the package directory layout looks like this: Layout
