The Ultimate Guide to Aggregator Pattern in Microservices

Aggregator Pattern in microservices and DDD plays a crucial role in simplifying the process of combining or aggregating data from multiple microservices into one unified response. In this video, we’ll break down the types of aggregators (Simple vs. Complex), explore implementation methods like Scatter-Gather, Chained, and Branch Patterns, and cover the key challenges you need to be aware of. Ideal for software engineers and architects designing scalable, distributed systems!

can you please tell what are you using to make these kind of animations, ,these are looking very good

[ArjunKumar-zukl]

Wonderful, 2 days back interviewer asked me the same question by calling Service1 to Service2 to Service3 and said I am violating Microservices architecture. I didn't know this. Thank you...

Pls make a video for multithreding-multiprocessing

Would you mind explaining this further? I fail to see the difference between an aggregator and a BFF. Maybe I was using the wrong name for the same thing? Or the difference between aggregator and BFF is that aggregator still have a domain rather just "combining requests"?

Good video, but I would say that you're mixing Aggregator with Splitter in some parts of your video.
Splitter - just splits request into multiple, while Aggregator - groups multiple responses into 1.

These aggregator/splitter (and many more, like patterns are well described in book "Enterprise Integration Patterns" by Gregor Hohpe.

I would also suggest to take a look at Kafka ecosystem, more specifically at KSQL and Flink. These do exactly what is described in this video.

The animation you used in your video is awesome, thanks for contributing such a great content. Can you please let me know which software did you used to create your video.

Hi can we use graph ql here to get only required from multiple services and aggregate?

[ArjunKumar-zukl]

What is this Aggregator Pattern looks like in terms of code? Microservices we can say we have controller, service classes and all?
