Inside ksqlDB: How Streaming Joins Work in ksqlDB

https://cnfl.io/inside-ksqldb-module-4 | One of the most common requirements in stream processing is to enrich one stream of data with information from another. In this video, Michael Drogalis (Principal Product Manager, Confluent) explains how ksqlDB's join capability works using the example of a stream-table join. Both the table and stream are built from Apache Kafka® topics, but how the data is treated by ksqlDB differs based on the type of object modeled. Tables in ksqlDB enable event stream data to be modeled as state, and so joined to a stream of events for lookup purposes.
