Recently, we have witnessed the emergence of new data stream management systems that can scale up to a large number of machines for the real-time processing of big data. These systems typically provide a procedural programming interface with their own APIs. However, to enable the rapid development of applications, it is desirable to support a declarative interface with clear processing semantics, such as window SQL. This paper examines the programming interfaces of the state-of-the-art data stream management systems and discusses the necessity of SQL support to help users write stream queries easily and in an integrated manner.
