Can you explain the difference between synchronous and asynchronous transactions in the context of Modern Transaction?

Synchronous transactions assume that the calling thread waits for the operation to complete before continuing. This means that execution is blocked until the transaction finishes successfully or with an error.

Asynchronous transactions allow initiating an operation and continuing execution without waiting for the result. The transaction's result or status is processed later, for example, through a callback, Future, or other mechanisms.

In the context of Modern Transaction:

• Synchronous transactions are easier to understand and debug but may reduce performance due to blocking.
• Asynchronous transactions improve system responsiveness and scalability but require more complex logic for handling and state control.

Example: during order payment, a synchronous transaction will wait for payment confirmation, while an asynchronous one initiates the payment and continues working, processing the result later.
