Streaming is necessary to handle data rates and latency but SQL is unquestionably the lingua franca of data. Where do the two meet?
Apache Calcite is extending SQL to include streaming, and the Samza, Storm and Flink are projects are each building it into their engines. In this talk, Julian Hyde describes streaming SQL in detail and shows how you can use streaming SQL in your application. He also describes how Calcite’s planner optimizes queries for throughput and latency.
Julian Hyde gave this talk at the first Kafka Summit, San Francisco, 2016/04/26.
