Polling (Polling/Consumer)

Polling, or polled operation refers to actively sampling the status of an external data source by a client program as a synchronous activity. Polling is most often used in terms of I/O, and is also referred to as polled I/O.

Polled I/O is a paradigm by which a process (in DocFamily's case DocBase) waits and monitors a data source until the source is ready to deliver data.
