Were data requests in your last project processed synchronously?

In my last project, data queries were primarily processed synchronously. This meant that when executing a query, the thread waited for a response from the database or service before continuing.

This approach is simple to implement and debug but can lead to blocking and reduced performance, especially if queries take a long time.

In some cases, an asynchronous approach was used, for example, with CompletableFuture or reactive libraries, to avoid blocking the thread and improve application responsiveness.
