Appirio Event Framework Library

Appirio Microservices should follow this model for asnychronous notification of events via a raw json payload. This library provides a Java implementation for our standard service stack.

• Publishers publish objects representing events to topics. Publishers must provide a unique application name. Objects should carry a unique identifier to allow subscribers to determine duplicate events.
• Each subscribing application must identify itself by a unique application name. A subscriber may have multiple workers reading messages on the same application, but a message will be delivered at least once per subscriber. Subscribers must be capable of receiving the same event multiple times without side affect.

Credentials

Provide AWS credentials in ~/.aws/credentials (where ~ is home directory of user running service)

_IAM_username]
access_key_id = BLAHBLAHBLAH
secret_access_key = blahBlahBlahBlahBlah

Usage

rt com.appirio.event.Topic;
rt com.appirio.event.Publisher;
rt com.appirio.event.Subscriber;

ic class TestModel {
private String testString;
public TestModel() {
}
public TestModel(String testString) {
    this.testString = testString;
}
public String getTestString() {
    return testString;
}


isher pub = new Publisher("PublisherAppName", "TopicName");
criber sub = new Subscriber("PublisherAppName", "TopicName", "SubscriberAppName");

Publish(new TestModel("hello"));

ng json = sub.getMessages()[0];
r
Model testReceived = (TestModel) sub.getItems(TestModel.class)[0];
