The Sessionize function maps each click in a session to a unique session identifier. A session is defined as a sequence of clicks by one user that are separated by at most n seconds.

The function is useful both for sessionization and for detecting web crawler ("bot") activity. It is typically used to understand user browsing behavior on a web site.

Sessionize is a SQL-MapReduce function. Sample code is included with the Aster SQLMapReduce Java API.
