Are there any other patterns for distributed transactions besides Saga?

Besides the Saga pattern for managing distributed transactions, there are other approaches:

• Two-Phase Commit (2PC) — a classic protocol that ensures transaction atomicity in distributed systems. It involves a prepare phase and a commit phase but can block resources and does not scale well.

• TCC (Try-Confirm-Cancel) — a pattern where each operation has three stages: try (reserve resources), confirm (commit), and cancel (rollback). It allows more flexible management of states.

• Eventual Consistency with compensating actions — instead of strict atomicity, the system allows temporary inconsistency, which is resolved by compensating operations.

• Orchestration and Choreography — architectural approaches to coordinating distributed transactions, where an orchestrator manages the process (e.g., using workflows), or components interact directly through events.

The choice of pattern depends on requirements for consistency, performance, and system complexity.
