Apache Ignite Pub/Sub Module
-----------------------------------

Pub/Sub module is a streaming connector to inject Pub/Sub data into Ignite cache.

Starting data transfer to Ignite can be done with the following steps.

1. Import Ignite Pub/Sub Module in Maven Project

If you are using Maven to manage dependencies of your project, you can add Pub/Sub module
dependency like this (replace '${ignite.version}' with actual Ignite version you are
interested in):

<project xmlns="http://maven.apache.org/POM/4.0.0"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0
                        http://maven.apache.org/xsd/maven-4.0.0.xsd">
    ...
    <dependencies>
        ...
        <dependency>
            <groupId>org.apache.ignite</groupId>
            <artifactId>ignite-pub-sub-ext</artifactId>
            <version>${ignite-pub-sub-ext.version}</version>
        </dependency>
        ...
    </dependencies>
    ...
</project>

2. Create an Ignite configuration file (see example-ignite.xml) and make sure it is accessible from the sink.

3. Make sure your data input to the sink is specified. For example `input.addSink(igniteSinkObject)`
