+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 Quarks IotProvider and IoTDevice with its command streams would be a
natural way to control the application. In this recipe we will just simulate a
"set poll period" command stream.
