How to do Distributed Transactions the RIGHT way? Microservices

Learning system design is not a one time task. It requires regular effort and consistent curiosity to build large scale systems. Moreover, every system has different requirements and meeting them requires expertise and people with varied and specific knowledge. There are a lot of resources to learn through videos. But not everyone enjoys that mode of learning. Instead some people understand things better by reading and thinking on the points put forward by the author. Such people can access these in different ways - blogs, articles and books. We have come up with this video to put light on one such aspect, that is - how microservices communicate using events.

Concise, simple visuals, clean and non-monotone speech, in short fabulous. Thank you for the video, rare to get a good overview in such short time!

[duffy]

Great video, thank you for putting these topics together

[ammabalasimha]

Explanation is very clear. Thanks a lot

[warriorfb]

Excellent. I look forward to watching your other videos. Thank you!

[AK-vxdy]

Very clear explanation of realy complicated things

[mohammedhuzaifa]

thanks dd for putting it in a way that is easy to understand

[rakeshkhuntia]

Thank you so much, Its very simple and clear explanation.

[Vaibhavatutube]

Brilliant explanation and presentation. Thanks!

[BitsAndBytes]

You explained it very well. Thank a lot

[phillipdino]

Such a grea video. Thank you for the explanation.

[rajchaurasiya]

Thank you mam for this valuable content 🙏

[premraj.m]

excellent, this is the perfect way to teach, 13mins went off very fast for me while watching this video

[evoxtorm]

We can also use Try-Confirm/Cancel approach also but we have to take care of out-of-order execution. But yes Saga are preferred due to their liner order of execution

[mhopado]

Thanks for explaining such complicated topics in simple way.
In real world you, will find the hybrid approach, where a orchestrator service keep track of the state of the transaction while passing the events from one service to other.
So in case of failure, the orchestrator will retry from the failure state of the transaction or revert back the previous operation.

Thank you so much. it is really great explanation for us. thank a lot

[sreejeshraj]

Thank you very much for your videos - excellent content, to the point. I have a request - can you please do a video comparing the similarities / differences between various styles of programming - messaging, event driven, asynchronous, reactive etc. I know that you have done vides on messaging, pub sub etc. - but a comparison video will make these concepts clear rather than doing separate videos for each topic.

[fcthrwz]

precise and simple. that created excellent content

[ashishjaiswal]

Nice explanation through animated slides seems do a lot of work thanks for explaining in intersting way, is there any source/link using java it will be helpful.

[blasttrash]

nice video. but one question at 6:58, while doing backward recovery, what if one of the backward step also fails? 😅Then state of our system is stuck as we cant move forward nor can we move backward.

Avoid distributed transactions at ALL costs in microservices - just use events and eventual consistency. This approach causes so many headaches I can't even list them all here
