KSQL is an open source, Apache 2.0 licensed streaming SQL engine that implements continuous, interactive queries against Apache Kafka®. KSQL makes it easy to read, write, and process streaming data in real-time, at scale, using SQL-like semantics. This offers an easy way to express stream processing transformations as an alternative to writing an application in Java or Python. KSQL provides capabilities such as streaming joins, aggregations, event-time windowing, and more!

Table-table joins in a relational database is a bit different, you can join a column from table1 to the primary key of table2.
Why do you need the same KEY in both tables?

Hi, good video. I would like to know if there is support for structured keys in the joins of the tables.
