# Tigon



![Tigon Logo](/tigon-docs/developer-guide/source/_images/tigon.png)



**Introduction**



**Tigon** is an open-source, real-time, low-latency, high-throughput stream processing framework.



Tigon is a collaborative effort between Cask Data, Inc. and AT&T that combines 

technologies from these companies to create a disruptive new framework to handle a diverse

set of real-time streaming requirements.



Cask Data has built technology that provides scalable, reliable, and persistent high-throughput

event processing with high-level Java APIs using Hadoop and HBase.



AT&T has built a streaming engine that provides massively scalable, flexible, and in-memory

low-latency stream processing with a SQL-like query Language.



Together, they have combined to create **Tigon**.



There are many applications that can take advantage of its features:



- Ability to handle extremely large data flows;

- Exactly-once event processing using an app-level Java API with consistency, reliability, and persistence;

- Streaming database using a SQL-like language to filter, group and join data streams in-memory;

- Runs collections of queries using pipelined query plans;

- Able to transparently handle complex record routing in large parallelized implementations;

- Runs and scales as a native Apache Hadoop YARN Application;

- Reads, writes, and tightly integrates with HDFS and HBase;

- Supports a significant amount of parallelization;

- Fault-tolerance and horizontal scalability without burdening the developer;

- Enterprise security features with debugging, logging, and monitoring tools; and

- Simpler programming model, tools and UI; and

- Open-source software and development process.

[Guides and other documentation](http://docs.cask.co/tigon/current/en/index.html).



## Is It Building?

------------------------------------------------------------------

[Bamboo Build](https://builds.cask.co/browse/TIG)                 

[GitHub Version](https://github.com/caskdata/tigon/releases/latest) 



## Getting Started



### Prerequisites



Tigon is supported on *NIX systems such as Linux and Macintosh OS X.

It is not supported on Microsoft Windows.



To install and use Tigon and its included examples, there are a few prerequisites:



  1. JDK 6 or JDK 7 (required to run Tigon; note that $JAVA_HOME should be set)

  2. GCC

  3. G++

  4. Apache Maven 3.0+ (required to build the example applications)

  

Note: To run the TigonSQL Stream Engine outside of Tigon, libz, Perl 5.x, and Python 3.x are required.



### Download



Pre-compiled sources and related files can be downloaded in a zip file: 

[tigon-developer-release-0.2.1.zip.](http://repository.cask.co/downloads/co/cask/tigon/tigon-developer-release/0.2.1/tigon-developer-release-0.2.1.zip)



### Install 



Once the download has completed, unzip the file in a suitable location.



### Run Instructions



To run Tigon in standalone mode:



    $ run_standalone.sh   



To run Tigon in distributed mode:



    $ run_distributed.sh  



### Building from Source



You can also build Tigon directly from the latest source code:



    git clone https://github.com/caskdata/tigon.git

    cd tigon

    mvn clean package -DskipTests -Pdist



After the build completes, you will have a distribution of Tigon under the

`tigon-distribution/target/` directory.  



Take the `tigon-sdk-.zip` file and unzip it into a suitable location.



## Getting Started Guide



Visit our web site for a [Getting Started Guide](http://docs.cask.co/docs/tigon/current/en/getting-started.html)

that will guide you through installing Tigon and running an example.  



## Where to Go Next



Now that you've had a look at the Tigon SDK, take a look at:



- Examples, located in the `/tigon-examples` directory of Tigon

- [Online Examples](http://docs.cask.co/tigon/current/en/examples/index.html) 

  (demonstrating basic features of Tigon) are located on-line

- [Reference Applications:](https://github.com/caskdata/tigon-apps)

  - [AdNetworkFlow:](https://github.com/caskdata/tigon-apps/tree/develop/AdNetworkFlow)

    Demonstrates using Tigon to write a realtime bidding (RTB) advertisement framework

  - [ClickStreamFlow:](https://github.com/caskdata/tigon-apps/tree/develop/ClickStreamFlow)

    Demonstrates using TigonSQL to write a webpage click stream data processing application.

- Developer Guides, located in the source distribution in `/tigon-docs/developer-guide/source`

  or [online](http://docs.cask.co/tigon/current/en/developer.html)



## CDAP



Tigon is the realtime stream processing framework used in the Cask Data Application Platform ([CDAP](http://cdap.io)).

CDAP provides a high-level [Dataset](http://docs.cask.co/cdap/current/en/developers-manual/building-blocks/datasets/index.html) abstraction for User Data Stores 

and allows developers to interact with them in their flowlets. In addition to the Dataset abstraction, CDAP integrates Batch Processing with

MapReduce and Spark support. By combining these with security, metrics, and an intuitive GUI, CDAP greatly simplifies Big Data application development. 

If you like the features and architecture of Tigon, we recommend that you take a look

at [CDAP](http://github.com/caskdata/cdap).



## How to Contribute



Interested in helping to improve Tigon? We welcome all contributions, whether in filing detailed

bug reports, submitting pull requests for code changes and improvements, or by asking questions and

assisting others on the mailing list.



### Bug Reports & Feature Requests



Bugs and suggestions should be made by [filing an Issue](https://issues.cask.co/browse/tigon).



### Pull Requests



We have a simple pull-based development model with a consensus-building phase, similar to Apache's

voting process. If you’d like to help make Tigon better by adding new features, enhancing existing

features, or fixing bugs, here's how to do it:



1. If you are planning a large change or contribution, discuss your plans on the `cask-tigon-dev`

   mailing list first.  This will help us understand your needs and best guide your solution in a

   way that fits the project.

2. Fork Tigon into your own GitHub repository.

3. Create a topic branch with an appropriate name.

4. Work on the code to your heart's content.

5. Once you’re satisfied, create a pull request from your GitHub repo (it’s helpful if you fill in

   all of the description fields).

6. After we review and accept your request, we’ll commit your code to the cask/tigon

   repository.



Thanks for helping to improve Tigon!
