    +title: Changing a Polled Source Stream's Period
    +---
    +
    +The [Writing a Source Function](recipe_source_function.html) recipe introduced the basics
of creating a source stream by polling a data source periodically.
    +
    +Oftentimes, a user wants the poll frequency to be adaptable rather than static.  For
example, an event such a sudden rise in a temperature sensor may motivate more frequent polling
of the sensor and analysis of the data until the condition subsides.  A change in the poll
frequency may be driven by locally performed analytics or via a command from an external source.

> A use case is something like:  an application wants to increase the poll frequency /
rate of analytics once some trigger condition occurs.  The trigger condition may be detected
by local analytics.  Or perhaps the change in poll frequency will be the result of receiving
an IotDevice command.
