2.3 Implementation examples of using CQL to process stream data

The implementation examples explained in this section are based on the information covered in 2.2 Using CQL to process stream data.

Using the temperature analysis system as an example, this section explains how query statements are used to process stream data. The following operations are demonstrated in these examples:
