Get started: https://cnfl.io/apache-flink-sql-modu... | Apache Flink® SQL makes it easy to implement analytics that summarize important attributes of real-time data streams.

There are four different types of time-based windows in Flink SQL: tumbling, hopping, cumulating, and session. Learn how these various window types behave, and how to work with the table-valued functions that are at the heart of Flink SQL’s support for windowing.

For more information, check out the Apache Flink SQL course on Confluent Developer: https://cnfl.io/apache-flink-sql-modu...
