What microservices patterns are you aware ? let's assume that there is a microservice based architecture and service A is calling service B which in turn service C. If service b fails, how will you manage transaction and logging ?

Question

Accepted Answer

Use compensating transactions and distributed tracing for managing transaction and logging in case of service B failure.

Implement compensating transactions to rollback changes made by service B in case of failure.
Use distributed tracing to track the flow of requests and identify where the failure occurred.
Implement retry mechanisms to handle transient failures in service B.
Use circuit breakers to prevent cascading failures in the system.
Implement centralized logging to capture logs from all services involved in the transaction.
