+ *
+ * A sampled event stream can be useful for logging high frequency events in
+ * a production environment where you only need an idea of what is happening
+ * and are not concerned with capturing every occurrence. Since the decision to
+ * handle or not handle a particular event is determined randomly, the
+ * resulting sampled log is not guaranteed to contain 1/N of the events that
+ * occurred in the application, but based on the Law of large numbers, it will
+ * tend to be close to this ratio with a large number of attempts.
