Count

Count is a collector function designed for testing and demo purposes. It generates a sequence of numeric values, starting at 1 and incrementing by 1 up to the configured maximum. Each value is emitted as a separate record. When the maximum is reached, Count stops emitting records.                                                                  

For an example of how you can use Count in a stream, see My first stream.

Input and output data
