Before diving into implementation, define what you need to log. For query performance, you might want to capture: - Query text - Execution time - User ID - Query parameters - Timestamp ### Step 2: Use Asynchronous Logging Asynchronous lo…

While asynchronous logging using `QueueHandler` and `QueueListener` is generally simpler and easier to implement, a logging queue can offer more flexibility and control over log entry processing. This is particularly useful when you need to…
