A definite +1 for this feature, thanks for your effort Till! Really look forward to the POC foundation and would like to help contribute where-ever possible.
Pattern matching along with event time support seems to be another major breakthrough for stream processing framework options currently on the table. At our company, we've been using Flink to implement pattern matching very similar to the use cases detailed in Till's design doc for adtech related applications. A comprehensive and expressive DSL for these applications will be fantastic.
