fantastic explanation , can u please make a video for demo of SAGA theoretically it's clear . but practially no. or u can give some link video which explain saga demo, thanks
Thank you for the lovely video,its just everyone is talking about theory can you please help us out with the code,i mean if you can show us small POC with spring boot and any db will be really appreciated.
What do you mean by complete 'part of the transaction'. How a message which is supposed to listen by some other queue is listening by service B (Your cyclic dependency logic) . This can be the last statement in Interview. ClientRequest should go to some service and from there Msgbroker should come into the picture. If txn successful for service A then msg is sent on some topic which is listening by B .... Same for orchestrator as well client should not interact with orchestrator at first step
you are giving some noun to different componentlike orchestrator (saga orchestrator ) this does n't tell that it is another service or progranm logic(like we have spring cloud) o it is a software like consul. So please clarify by giving example of the ochestrator or component
Yes. but the DB we choose should be very much fast so I can say Redis can be of great help here. Or we can go with in memory logging as well but in this case there will be compromise of data loss in case of system failure. Or we can write it in system files as well, as the log file is short term and as soon as transaction is complete we can process the log file data in any other DB and clean the files from the system.
as far as I know, the compensation transactions in SAGA should be idempotent and retriable. We have to design our comp transactions in a such a way that, even if the error occurs it has to perform retry (we can use circuit breaker design pattern b/w different microservices)

I like this video because it explains the problem that the SAGA pattern solves
Hey Arvind, I want to say that you are doing an awesome job, really a fantastic work.
Thanks Jitendra for the kind words.
Literally waiting for this. Thanks alot.
Great Job ! Thank you for the detailed explanation
very clean and crisp explanation, thanks !!
Can we expect poc for this.
Yes Akshay. Even I am excited about it's POC. As soon as it's completed will upload that.
Thank you for the detailed explanation, can you please do some poc on the same?
I have planned for the demo in the ongoing microservices demo series
fantastic explanation , can u please make a video for demo of SAGA theoretically it's clear . but practially no. or u can give some link video which explain saga demo, thanks
The explanation is good,can you please post some videos on the code implementation.

Glad to hear, it was helpful.

Awesome ! good job

Thank Arvind, Can pls share any link for the resource code saga design pattern any document
Is the Saga Log will be a DB Table?
Yes. but the DB we choose should be very much fast so I can say Redis can be of great help here.
Or we can go with in memory logging as well but in this case there will be compromise of data loss in case of system failure.

Hi Arvind, Nice explanation. just one question. what happened in case of compensation request failed. How other microservices are rollback.
as far as I know, the compensation transactions in SAGA should be idempotent and retriable. We have to design our comp transactions in a such a way that, even if the error occurs it has to perform retry (we can use circuit breaker design pattern b/w different microservices)
Nice1
Video Transcript in English language not working pls help
Where can I find implementation of SAGA?
It's not there on the channel yet.. I am going to start soon Microservices demo series where all the patterns will be implemented including saga
