Simple Cassandra Client

Author: Chris Hedley

This application is a simple [Cassandra] 1 client which will attempt to connect to a provisioned [Cassandra] 1 service in CloudFoundry. We assume that you already have Cassandra as a Service setup in your Cloudfoundry deployment.

Building

The project is compiled and packaged using [Gradle] 2. The project can be built using gradlew (*nix) or gradle.bat (Windows) if you do not have [Gradle] 2 installed. Note, for the rest of this documentation we will refer to Gradle commands as gradle. If you do not have Gradle installed then change the gradle command for that of your environment.

Running the gradle war. following command will create a war file in $PROJECT_HOME/build/libs. This war can be pushed to CloudFoundry using the [vmc] 3 tool.

Deploying

The build script also support deploying an application and creating a Cassandra Service. To use this feature follow the below steps:

1. Open up build.gradle and add your Cloudfoundry username and password to the cloudfoundry hash (lines 42 & 43)
2. Change the target (line 41) and the URI's (line 46) if required.
3. Run the command gradle war to build the war artifact.
4. Run the command gradle cf-add-service to create the test Cassandra service.
5. Tun the command gradle cf-push tp push create the app in Cloudfoundry.

Note steps 2,3 and 4 can be replaced with the single command gradlew war cf-add-service cf-push

You should be left with a new Cassandra Service called 'cassandra-test-service' and a new application called simple-cassandra-client. The application can be accessed at the urls http://c.cloudfoundry.test' and 'http://cassandra-test.cloudfoundry.test (interchange your Cloudfoundry target in the urls where required.)
