> My requirement is to load data from a file and polling with a specific frequency (say every 1 second). 
> I found Topology.poll() can do this, but it requires a Supplier parameter and the get method is called periodically. With this way, I have to read the file content myself and create a Iterable instance, then a Supplier. 
> I want to use FileStreams.textFileReader() to handle the file reading. The problem is how to use it with Topology.poll() together? I could not find a way to do this. 
> Is there any way to do this? Or connectors does not support "polling" at all?
