Flink Forward Berlin 2017: Timo Walther - From Streams to Tables and Back Again: A Demo of Flink's Table & SQL API

446 views

Published on

Flink’s DataStream abstraction is a powerful API which lets you flexibly define both basic and complex streaming pipelines. However, many users need an API which quickly solves 80% of their use cases where simple tasks can be defined using little code. Therefore the community has made effort to add relational APIs to Apache Flink, a standard SQL API and a language-integrated Table API. A large amount of contributors push the development quickly. In this talk, we show the current status of the APIs in a live demo. Among others, we demonstrate the support of retractions in Dynamic Tables and different kinds of aggregations such as SQL OVER windows, GROUP BY windows, and non-windowed aggregates.
