XStream: Declarative authoring of distributed, elastic stream processing pipelines
28 August 2017
In this talk I present XStream, a DSL for writing stream processing queries that are to be executed across distributed network nodes. XStream is used in a stream processing system developed at Nokia Bell Labs to do real-time processing of data and media streams. I will briefly discuss the DSL and how queries get compiled. XStream started off as an external DSL but was later revised to become an embedded DSL.
