Apache Kafka - Real-time Stream Processing (Master Class) - Understanding Local Vs Remote State Store

The video tutorial explains the concept of interactive queries in Kafka Streams, focusing on the importance of state stores. It discusses the distinction between local and remote state stores in distributed applications and how Kafka Streams APIs facilitate querying these stores. The tutorial also covers the use of an RPC layer, such as REST API, to abstract data retrieval from local or remote stores, ensuring seamless data access for external applications.
