Installing Quine

Quine is a key participant in a streaming event data pipeline that consumes data, builds it into a graph structure, runs computation on that graph to answer questions or compute results, and then stream them out. Quine combines the real-time event processing capabilities of systems like Flink and kSQLdb with the graph data structure found in graph databases like Neo4J and Tigergraph.

There are multiple ways for you to install Quine, select the one that is best for your environment from the list below.

Method Description
Docker Container If you already have Docker, this is the quickest way to get up and running with the minimum setup time and impact to your environment.
Download Java distribution file Download the jar file to run locally on your laptop or development server. Running the jar file locally is the most flexible way to evaluate Quine.
Build from source Need to do a deeper evaluation of how Quine operates? Clone the open source repository from GitHub and dig in!
Cloud hosted by thatDot Are you interested in the Quine Enterprise features? Contact our sales team to set up an evaluation environment in your cloud provider of choice.

Follow the steps below to install Quine for use in your environment.


Docker Container

Docker allows you to install a containerized version of Quine for evaluation.

Prerequisites

  • Host Environment - You need a Mac, Windows, or Unix host server to run Docker. Please be sure that your host meets the system requirements outlined in the proceeding links.
  • Docker Desktop - Instructions on how to install Docker can be found on the official Docker website.

Install and start the Quine container

The Quine Docker image is distributed via Docker Hub and can be installed and launched with a single command.

  1. Open a terminal window
  2. With the Docker desktop application running, issue the following command
docker run -p 8080:8080 thatdot/quine

If successful, you will see a message similar to the following appear in the terminal.

}

You can connect to the Quine exploration UI by entering http://127.0.0.1:8080 into your browser.

Shutdown Quine

POST to the admin/shutdown endpoint to gracefully shutdown Quine and stop the Docker container.

curl -X "POST" "http://127.0.0.1:8080/api/v1/admin/shutdown"

Both Quine and the Docker container will shutdown and exit. If successful, you will see a message similar to the following appear in the terminal and the container will have a status of exited in the Docker desktop.

Distribution File

Using a distribution file to run Quine locally provides the most flexibility …

  • Evaluate Quine using your hardware of choice
  • Make changes to the Quine configuration file
  • Launch Quine recipes
  • Benchmark Quine’s performance running different versions of Java

Prerequisites

You will need the following in order to run Quine in your environment.

  • Java JRE version 11 or greater - instructions for how to install Java can be found on the official Java web site.

Download the Quine Distribution File

Quine is distributed as a pre-built Java jar package that you download and run on your local laptop or server.

  1. Download the jar file from the quine.io download page.
  2. Store the jar file in a working directory

We recommend storing the Quine jar file in the same directory that you plan to use during your evaluation and development.

On a Mac, this process would look similar to this.

  • Selecting the JAR DOWNLOAD button prompted the browser to download the latest version of Quine and store it in the ~/Downloads directory.
  • Once the download completes, issue the following commands to move Quine into a directory that you can use for evaluation and testing.
❯ mkdir gettingStarted
❯ cd gettingStarted
❯ mv ~/Downloads/quine-1.3.2.jar .
❯ ls -l
total 460088
-rw-r--r--@ 1 quine  staff  220704180 Aug 25 09:22 quine-1.3.2.jar

Start Quine

Once you have the Quine package stored locally, you are ready to launch Quine for the first time.

To launch Quine, issue the following command.

❯ java -jar quine-1.3.2.jar

If successful, you will see a message similar to the following appear in the terminal.

Prerequisites

Quine is written in Scala and Node JS. Please review the README.md file in the GitHub repository for most up to date requirements to build Quine from source.

  • Java JDK 11 or greater
  • Scala SBT version 1.7.1 or greater
  • Node version 16
  • Yarn version 0.22.0 or greater

Clone the Quine repository from GitHub

❯ mkdir quineEvaluation
❯ cd quineEvaluation
❯ git clone git@github.com:thatdot/quine.git
Cloning into 'quine'...

Build Quine

❯ cd quine
❯ nvm use 16
Now using node v16.15.1 (npm v8.11.0)
❯ sbt quine/assembly
[info] welcome to sbt 1.7.1 (Homebrew Java 11.0.16.1)

... <build details removed> ...
[success] Total time: 78 s (01:18), completed Aug 25, 2022, 9:54:42 AM

If successful, the sbt tool will configure your environment, build, and package Quine into a jar file located in the target directory.

❯ find . -name "quine-*.jar"
./quine/target/scala-2.12/quine-assembly-1.3.2+n.jar

Start Quine

Once that you have successfully built and assembled the Quine jar file, we recommend copying that file into a working directory to make it easier to evaluate Quine.

❯ cp $(find . -name "quine-assembly-*.jar") ..
❯ cd ..
❯ ls
quine/  quine-assembly-1.3.2+n.jar

Then you can launch Quine in the same way that you would launch the distribution file.

❯ java -jar quine-assembly-1.3.2+n.jar

If successful, you will see a message similar to the following appear in the terminal.

Graph is ready
Quine web server available at http://127.0.0.1:8080
