public class TemporalJoinSQLExample
extends Object

Example for demonstrating the use of temporal join between a table backed by a DataStream and a table backed by a change log stream.

In particular, the example shows how to

• create a change log stream from elements
• rename the table columns
• register a table as a view under a name,
• run a stream temporal join query on registered tables,
• and convert the table back to a data stream.

The example executes a single Flink job. The results are written to stdout.
