This document is the official specification for SPL. SPL is a programming language for high-performance distributed stream processing systems. An SPL program describes a data flow graph, where the vertices are operator instances and the directed edges are streams. SPL is extensible by allowing users to define their own primitive operators in a native language, and by allowing users to define their own parameterizable composite operators in SPL itself. Furthermore, SPL permits users to dynamically compose independently launched streaming programs. Thanks to its generality, SPL makes it easy to express applications from a large variety of domains, including but not limited to financial trading, transportation monitoring, manufacturing control, security, healthcare, etc.
