             Summary: Interactive Query v2
                 Key: KAFKA-13479
                 URL: https://issues.apache.org/jira/browse/KAFKA-13479
             Project: Kafka
          Issue Type: New Feature
          Components: streams
            Reporter: John Roesler


Kafka Streams supports an interesting and innovative API for "peeking" into the internal state of running stateful stream processors from outside of the application, called Interactive Query (IQ). This functionality has proven invaluable to users over the years for everything from debugging running applications to serving low latency queries straight from the Streams runtime.

However, the actual interfaces for IQ were designed in the very early days of Kafka Streams, before the project had gained significant adoption, and in the absence of much precedent for this kind of API in peer projects. With the benefit of hindsight, we can observe several problems with the original design that we hope to address in a revised framework that will serve Streams users well for many years to come.
