Have you created a database for processing requests in synchronous or asynchronous mode?

In Go projects, asynchronous request processing to the database is often used to avoid blocking the main execution thread and to efficiently utilize goroutines. For example, goroutines and channels can be used to perform requests in parallel and process results as they become available.

An example of an asynchronous database query using goroutines:

func queryDBAsync(db *sql.DB, query string, results chan<- *sql.Rows, errors chan<- error) {
    go func() {
        rows, err := db.Query(query)
        if err != nil {
            errors <- err
            return
        }
        results <- rows
    }()
}

However, in some cases, such as simple or sequential operations, a synchronous mode may be used, where requests are executed sequentially and the calling thread waits for their completion.
