CSI System-to-System Integration Patterns 3

Question 1

Which pattern splits a large message into smaller chunks, routes them independently, and reassembles the results before delivering to the recipient?

Accepted Answer

Splitter-Aggregator

Answer

The Splitter-Aggregator pattern breaks a message into parts, processes them independently, then recombines the outputs into a single response.

Question 2

An integration engineer needs to route an incoming order message to different fulfillment systems based on the product category field. Which EIP pattern applies?

Accepted Answer

Content-Based Router

Answer

Content-Based Router inspects message content (such as a field value) to determine which downstream endpoint should receive it.

Question 3

What problem does the 'Claim Check' enterprise integration pattern solve?

Accepted Answer

Handling large payloads by storing them externally and passing only a reference token

Answer

Claim Check stores bulky message content in external storage and passes a lightweight token through the messaging channel, reducing channel load.

Question 4

In a choreography-based microservices integration, how do services coordinate their actions?

Accepted Answer

Each service reacts to events and publishes its own events without a central controller

Answer

Choreography relies on each service listening for events and emitting its own events, forming a decentralized coordination without a central orchestrator.

Question 5

Which protocol is commonly used for lightweight, machine-to-machine messaging in IoT system integration due to its low bandwidth overhead?

Accepted Answer

MQTT

Answer

MQTT is a publish-subscribe protocol designed for constrained environments, offering minimal overhead ideal for IoT device-to-platform integration.
