Can you list the main types of sagas in microservice architecture?

In microservices architecture, the main types of sagas can be divided into two approaches:

1. Choreography

   • Each microservice independently performs its part of the transaction and publishes events that other services subscribe to.
   • There is no central coordinator; control is distributed.
   • Example: an order service publishes an "Order Created" event, and the payment service listens to this event to initiate payment.

2. Orchestration

   • A central component (orchestrator) manages the execution of saga steps, calling microservices in sequence.
   • The orchestrator controls the sequence and compensating actions in case of errors.

Both approaches help ensure data consistency in a distributed system without using distributed transactions.
