I was wondering around about prepare phase and commit phase. So, in prepare phase we save the resource with prepare/any-other status and in commit phase we simply the same resource.
It was very clear. Thanks! Looking forward how saga resolve these two problem.❤❤❤

Very clear and would please try to show how we lock the resources in this case?

Appreciate for the great content but 1qq this gives a feel of more or less Saga orchestrator pattern. If you can clear out how is it different & in real time should we go for saga or 2PC?

Then ? when to use saga Vs 2pc i am so confused on both
