It is inspired by recent advances in the [Akka](https://github.com/akka/akka) framework and a desire to improve on existing streaming frameworks.\n\nThe 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.\n\n![](http://gearpump.apache.org/img/dashboard.gif)\n\nWe model streaming within the Akka actor hierarchy.\n\n![](docs/contents/img/actor_hierarchy.png)\n\nPer initial benchmarks we are able to process near 18 million messages/second (100 bytes per message) with a 8ms latency on a 4-node cluster.\n\n![](docs/contents/img/dashboard.png)\n\nFor steps to reproduce the performance test, please check [Performance benchmark](http://gearpump.apache.org/releases/latest/introduction/performance-report/index.html).\n\n## Useful Resources\n\n* Read the [Introduction on TypeSafe's Blog](https://typesafe.com/blog/gearpump-real-time-streaming-engine-using-akka)\n* Learn the [Basic Concepts](http://gearpump.apache.org/releases/latest/introduction/basic-concepts/index.html)\n* How to [Develop your first application](http://gearpump.apache.org/releases/latest/dev/dev-write-1st-app/index.html)\n* How to [Submit your first application](http://gearpump.apache.org/releases/latest/introduction/submit-your-1st-application/index.html)\n* Explore the [Maven dependencies](http://gearpump.apache.org/downloads.html#maven-dependencies)\n* Explore the [Document site](http://gearpump.apache.org)\n* Explore the [User Mailing List](http://mail-archives.apache.org/mod_mbox/incubator-gearpump-user/)\n* Report an [issue](https://github.com/gearpump/gearpump/issues)\n\n## How to Build\n\n1). Clone the Gearpump repository\n\n```bash\n  git clone https://github.com/gearpump/gearpump.git\n  cd gearpump\n```\n\n2). Build package\n\n```bash\n  ## Please use scala 2.12\n  ## The target package path: output/target/gearpump-${version}.zip\n  sbt clean +assembly +packArchiveZip\n```\n\n  After the build, there will be a package file gearpump-${version}.zip generated under output/target/ folder.\n\n  To build scala document, use\n```bash\n   ## Will generate the scala doc under target/scala_2.xx/unidoc/\n   sbt unidoc\n```  \n\n  **NOTE:**\nThe 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.\nFor windows:\n\n```bash\nset HTTP_PROXY=http://host:port\nset HTTPS_PROXY= http://host:port\n```\n\nFor Linux:\n\n```bash\nexport HTTP_PROXY=http://host:port\nexport HTTPS_PROXY=http://host:port\n```\n\n## How to do style check before submitting a pull request?\n\nBefore submitting a PR, you should always run style check first:\n```\n  ## Run style check for compile, test, and integration test.\n  sbt scalastyle test:scalastyle it:scalastyle\n```\n\n## How to generate the license report to generate a list of all dependencies \n```\n  sbt dumpLicenseReport\n```\n\n## How to generate dependencies by declared license\n```\n  sbt dependencyLicenseInfo\n```\n\n## Contributors (time order)\n\n* [Sean Zhong](https://github.com/clockfly)\n* [Kam Kasravi](https://github.com/kkasravi)\n* [Manu Zhang](https://github.com/manuzhang)\n* [Huafeng Wang](https://github.com/huafengw)\n* [Weihua Jiang](https://github.com/whjiang)\n* [Suneel Marthi](https://github.com/smarthi)\n* [Stanley Xu](https://github.com/stanleyxu2005)\n* [Tomasz Targonski](https://github.com/TomaszT)\n* [Sun Kewei](https://github.com/skw1992)\n* [Gong Yu](https://github.com/pangolulu)\n* [Karol Brejna](https://github.com/karol-brejna-i)\n\n## License\n\nGearpump itself is licensed under the [Apache License (2.0)](http://www.apache.org/licenses/LICENSE-2.0).\nFor library it used, please see [LICENSE](https://github.com/gearpump/gearpump/blob/master/LICENSE.bin).\n\n## Acknowledgement\n\nThe netty transport code work is based on [Apache Storm](http://storm.apache.org).
