What it shows

  • An orchestrator coordinates sequence using persistent state machines.
  • Compensating transactions reverse partial work in reverse order.
  • Trades strict ACID isolation for eventual consistency across boundaries.

The takeaway

Sagas ensure distributed consistency by executing explicit semantic rollbacks when downstream steps fail.
