I love watching your videos, they all very informative I have few questions on CQRS Why we are not using any queues like Apache activemq or even kafka. Will it work same way in production. How we will implement distributed logging in CQRS, Will spring sluthe and zipkin work here ?? How can you do SAGA/CQRS/Event sourcing without axon framework? Can you please make a video on that as well

How about saga choreography and orchestration with cqrs in eventuate tram in java?

[@anushabondalapati1267]

The video explained many things, very helpful, thank you. But I didn't understand what SAGA is doing, if any error happened we are reverting in catch block. Can't we do this without SAGA. Or did I miss anything?

Thanks for the excellent tutorial. Do you have any videos on Saga Choreography pattern. Thanks

[@heymanchan9007]

Thank you You have answered my biggest question recently: how to implement SAGA pattern? Any framework?

[@happy.s1ngh]

I was designing a Food Delivery app backend design. So I was wondering that is it appropriate to apply the CQRS or SAGA on all the microservies or only on the specific food odering microservice like when we make online order or on the all the microservices like creating a restaurant, address all these kind of microservices?

[@ashokkumar-cx6of]

Hi , I have created saga application same like u . But CommandGateway bean is not created? I used to create @Configuration also still bean is not created. What is the cause ?

[@avinashtiwari478]

Hi I have created application using axon 4.10.2 with spring boot 3.3.5. while running the order service, payment and shipment service only order service is creating initial data but while calling payment service commandHandler i am getting OUT_OF_RANGE [AXONIQ 2000] error. Could any one suggest solution. I tried by deleting events and snapshot and recreated database but still this issue i am getting.

[@lyricsalvids8706]

can you create how to secure microservices in springboot? with authentication and authorization

[@trunghale7835]

Many thanks your video, can you tell me where did you use orchestrator pattern in your example, and instead of use axon, can we use kafka?

[@DhirendraSingh1409]

Yes please provide a positive answer to this query

[@Arshadee]

Firstly thanks for a great and much needed tutorial. I have a question, how would I call the compensating transaction on any Saga service whereby the proceeding service in the SAGA is down / unavailable. So far it works fine if there is a failure on the proceeding saga service but not handling it if its down.

[@ahmedelbarqy4849]

I keep getting ForbiddenClassException when I send the command to the other microservice

[@giangnguyeninh4576]

which font in intellij are you using?

[@vishanth5863]

Compensating transaction will undo the records but the records are already committed right. Let's say as part of a transaction, account balance was increased and committed and the next event fails and compensating transaction is triggered. Before this undo the record, another request uses the increased account balance. How to handle this kinda scenarios? Please let me know or guide if any approach to handle this.

[@GauravSharma-wb9se]

Do we really need axon for saga....can't we do it without axon ?

[@DailyCodeBuffer]

Yes we can do

[@derrick3534]

Nice video. How do you replay events?

[@oguzoztnaz4986]

Thank you for this video. It helped a lot. But when I practice this code, I had a problem. My command is being triggered, I can see that on the Axon Dashboard, yet my event is not being published. Has anyone had the same problem?

[@pavankumarbasava618]

String and integer is working fine but when I try to pass complex objects to command handler and event handler it returns com.thoughtworks.xstream.converters.ConversionException: No converter. Can you help?

[@sathiskumarp]

Thanks for this video. I am able to understand the video. I have a couple of clarifications. If suppose we are using some third party payment service to handle the payments and let's assume payment was done and some issue with shipment. In this case, we need to call the third-party payment service by passing the cancel status? Also our payment service aswell

[@souvikpatra2737]

This is what i want . loved it bro. Could you please upload this kind of videos of spring boot like different design patterns of microservices. please please :)

Hi, Can I integrate Axon Framework with Amazon Simple Queue Service (SQS)?

[@АндрейБорденко]

Great video dude. What about DDD video with spring?

[@Sanchitgoel10]

This is an awesome video, just a small problem in my case whenever I follow your video by simultaneously coding I tend to face number of errors because the length of code before you run your application for the first time tends to be huge, is there a way I can run and test in between if all things are fine?

[@dpaulentertainment5642]

@DailyCodeBuffer i am confused between Choregraphy and Orchestration Pattern. do you have any video or blog for Choregraphy example Implementation? and what is our orchestrator in this example, does it created at axon end?

[@codingstyle9480]

In Choreography pattern, you do not have any Saga annotated class which manages the flow. This pattern is used where you have not lots of microservices(probably less than 10) . If more than 10 microservices, as it would be very difficult to code the flow of actions, Choreography pattern is used, which is coordinated. In Choreography pattern, you just send a command which is handled by command handler in an aggregate class in different or the same microservice, which handler fires an event, which event may be consumed by several microservice per command but many event handlers per event raised in both cases.

Hi bro. your tutorials are really insightful. even I learned many things from you. I had watched the given video till 1 hrs 50 min, It seems that you are not saving user record within database jdbc:h2:file:~/data/orderDB order table and also not maintaining data in user db and even Order created event is pulished but user records is not saved/updated for the user associtated with given order So was this a mistake or intentionally you did it? Please reply if possible that will be helpful

Hi Girish, Thank you so much and impressed with the details shared. Yes, you are correct. It is intentionally not save. User is kept one static in the tutorial and rest all the details are propagated and saved to the database. Hope this helps to solve your doubts Always happy to help

Nice Saga demo Shabbir. This saved my day. Please let me know.. 1. If we can push this PoC including Axon server into AWS EKS cluster too? 2. All of your microserves are okay to dpeloy in AWS EKS cluster too but I am new and first timer in Axon, so wondering if Axon server's deployment in AWS EKS is doable too? 2. Also as we want to use postgres db for each microservice in stead of in-memory db so I hope that won' t be a problem too. Please let me know. 3. If you have a more of a real time kind of working example/PoC on same requirements as mine (like deploying into AWS EKS cluster the services and axon server and databases), then please share it if possible.
