Client-Library’s asynchronous mode allows applications to perform potentially blocking operations asynchronously. This can be an enormous benefit to end-user applications using a GUI interface, because it allows application users to proceed with other work while waiting for blocked operations to complete.
Synchronous DB-Library applications are often improved by redesign as asynchronous Client-Library applications.
For more information on Client-Library’s asynchronous mode, see “Asynchronous programming”.
