Azure Stream Analytics provides a great solution for temporal queries of streams of data. The query language is pretty simple, especially if you have a background in SQL queries.
The list of built-in functions is a long list, ranging from aggregation, analytics, geospatial, records, scalars to the recently introduced anomaly detection.

- user-defined aggregates (UDA) written in Javascript
- Machine learning endpoint disguised as functions
