Very Well Explained...
The systems design is all well and good. But actually implementing it in an enterprise microservices architecture without using serverless and it being a mess; is a different thing.... Nice video!
Yesh Ben. Cannot agree more. Thats another reason why many companies does not use SAGAs for majority of their usecase. I'm going to create a hands-on series. Before that lots of people wanted to know how to handle exception scenarios in SAGAs, so created this one. Thanks for the feedback.
Excellent 👍
Really helpful, great explanation, thanks for the video.. 👍
Glad it was helpful!
Good content ajay... ❤️❤️❤️
Cool very useful Ajay
It's very basic explanation of saga pattern. Concept is very easy but when you are going to implement its very hard. Specifically which one to choose choreography or orchestration?? could you please make another video about how saga pattetn implement in the particular application.
Hi Ashish
I have done a basic implementation of saga pattern. It might be helpful for you.

Yesh Ashish. Thats next. I'm going to create a series. Before that lots of people wanted to know how to handle exception scenarios in SAGAs, so created this one. Thanks for the feedback.
Would appreciate an implementation. This is because the concepts are known, but the implementation that is difficult
Totally agree, concept is very easy but when you are going to implement its very hard. Specifically which one to choose choreography or orchestration??
Yesh Lau. Thats next. I'm going to create a series. Before that lots of people wanted to know how to handle exception scenarios in SAGAs, so created this one. Thanks for the feedback.
@@TechPrimers that's great news! Can't wait for the video :)
Please create a implementation in spring boot
I believe the Order service will only generate an order id and respond back to the app and now its app responsibility to call the payment service separately, on which the app page gets redirected through the payment gateway and the order is marked as payed after payment service again calls the order service with the order id and transaction id.

Ajay, can you make a video on feature flags and canary deployments
Sure chandan
Will do
Hi, i don't think cart service's database will be populated the minute we add something to the cart, i think it will stored locally in phone. To confirm this assumption i added something on my cart on website and then opened my app, the cart contents were not updated in the app.
I don't think based on login we can assume this because i also uninstalled the app, if it was stored in cart DB i would seen my items after installing again, which wasn't the case. Did i miss something?
I have done the same with Amazon. However the items stayed in web though i added in Mobile.
I guess everyone has their own implementation. So it's fair to say it's up to the product feature team to decide😉
@@TechPrimers agree, major players do the same like Zealand on, Walmart, adidas does preserve the dat across app or web.
