Developers must explicitly design a compensating transaction for every saga step that can commit before the overall process fails. Microservices.io states no automatic rollback is available — each reversal is coded separately.

Compensating transactions execute in reverse saga order. If steps T1, T2, T3 succeed but T4 fails, the system runs C3, C2, C1 in sequence, restoring each service's data to a consistent state.

A compensating transaction reverses a previously committed transaction. It is a core mechanism in the saga pattern, used to restore data consistency across services where traditional ACID rollback is not available.
