This has to be done in the Process development. Not in Analytics.
For example you can make a process with a FileWait action which will watch a specified directory every 10 seconds, indefinitely.
Have a look the attached process.

FileWait watches the "datafiles" directory and executes the "TreatFile" action for each file named "*.go". The idea is to bind an "ExecuteDelivery" action.
The SqlOperation action also has this kind of feature : use the parameters "Wait Nb Rows", "Wait Count Select", "Wait Poll Interval"...
If you don't want a permanent running process, you can set the timeout to some positive value, and schedule this process at your preferred periodicity.
