Streaming Expressions started from a few simple concepts:

* Stream sources that originate streams
* Stream decorators that transform streams
* A simple functional syntax to tie it all together

Streaming Expressions now have over 80 expressions & evaluators, conditional logic, variables & data structures. These functions form the basis of a sophisticated functional programming language that supports a large number of parallel computing use cases including: Parallel SQL, MapReduce, Machine Learning, Anomaly Detection, Streaming NLP, Graph Traversal & Time Series Analysis.

This talk will cover the evolution of the language to date & where Streaming Expressions will likely be headed in the future.
