Dynamic Configuration

Comcast Dynamic Configurattion - dynocon is on the mission of adapting the Configuration-as-a-Code concept.

Dynocon library allows your application to get access to the latest configuration changes without restarting.

JSON is a first-class citizen and supported out of the box as well as the traditional .properties format.

Installation

<dependency>
	<groupId>com.comcast.dynocon</groupId>
	<artifactId>dynocon-core</artifactId>
	<version>1.1.0</version>
</dependency>

Example

If your JSON configuration looks like this:

{
  "myPropertyName": "value1"
}

or you are using traditional .properties file:

myPropertyName = value1

You could always access the property as following:

public static final Property<String> MY_PROPERTY = new Property<>("myPropertyName", String.class);
... SNIP ...
Assert.assertEquals("value1", MY_PROPERTY.get());

If the value in the file will be updated, you don't need to restart the application, MY_PROPERTY.get() will return the new value.

See Wiki for a full description of the dynocon library.
