=== Launching a task from a Spring Cloud Stream
Allows a user to launch tasks from a stream. This is done by creating a sink that
listens for a message that contains a `TaskLaunchRequest` as its payload. The
TaskLaunchRequest contains the maven coordinates to the Task that is to be executed. It
also has a Map that contains the environment variables that will be used by the Task.
NOTE: If the payload is of a different type then the sink will throw an exception.
For example a stream can be created that has a processor that takes in data from a
http source and creates a `GenericMessage` that contains the `TaskLaunchRequest` and sends
the message to its output channel. The task sink would then receive the message from its
input channnel and then launch the task.
To create a taskSink a user needs to only create a spring boot app that includes the
following annotation `EnableTaskLauncher`. The code would look something like this:
```
@SpringBootApplication
@EnableTaskLauncher
public class TaskSinkApplication {
public static void main(String[] args) {
SpringApplication.run(TaskSinkApplication.class, args);
}
}
```
A sample Sink and Processor have been made available to you in the samples module
of the Spring Cloud Task project. To install these samples into your local maven
repository execute a maven build from the `spring-cloud-task-samples` directory with the
property `skipInstall` set to false. For example:
`mvn clean install -DskipInstall=false`.
==== Spring Cloud Data Flow
To create a stream in Spring Cloud Data Flow first we would want to register the Task Sink
Application we created. In the example below we are registering the Processor and Sink
sample applications using the Spring Cloud Data Flow shell:
```
module register --name taskSink --type sink --coordinates io.spring:tasksink:1.0.0.BUILD-SNAPSHOT
module register --name taskProcessor --type processor --coordinates io.spring:taskprocessor:1.0.0.BUILD-SNAPSHOT
```
To create a stream from the Spring Cloud Data Flow shell would look like this:
```
stream create foo --definition "http --server.port=9000|taskProcessor|taskSink" --deploy
```

= TaskProcessor
Is a stream processor that will accept messages with a string payload and create a
`TaskLaunchRequest` that it will send to the next app in the stream. The payload of the
message that is sent will be added to the properties of the `TaskLaunchRequest` under
the `payload` key.
By default the processor will add the timestamp-task sample coordinates if no task is
specified.
NOTE: if using defaults make sure to install the timestamp-task into your local maven repo
by executing the following build in the timestamp-task module:
[source,shell,indent=2]
----
$ ./mvnw clean install -DskipInstall=false
----
== The parameters offered by the TaskProcessor are as follows:
* *group* establishes the group for the task maven coordinates. Default is `io.spring`.
* *artifact* establishes the artifact for the task maven coordinates. Default is `timestamp-task`.
* *classifiers* establishes the classifier for the task maven coordinates. Default is null.
* *extension* establishes the extension for the task maven coordinates. Default is jar.
* *data-source-url* sets the spring_datasource_url for the task. Default is null.
* *data-source-driver-class-name* establishes the spring_datasource_driverClassName for the task. Default is null.
* *data-source-user-name* establishes the spring_datasource_username for the task. Default is null.
* *data-source-password* establishes the spring_datasource_password for the task. Default is null.
== Requirements:
* Java 7 or Above
== Build:
[source,shell,indent=2]
----
$ ./mvnw clean install -DskipInstall=false
----
== Dependencies:
The task processor requires an instance of Redis to be running.
