sscan

Iterates incrementally over members contained in a set of unique values, using a cursor.

An iteration starts when the cursor is set to 0.
To get the next page of results, simply re-send the request with the updated cursor position provided in the result set.

The scan ends when the cursor returned by the server is 0.
