------------------------------------
Summary: Add Scala API for CEP's pattern definition
Key: FLINK-3414
URL: https://issues.apache.org/jira/browse/FLINK-3414
Project: Flink
Issue Type: Improvement
Components: CEP
Affects Versions: 1.0.0
Reporter: Till Rohrmann
Priority: Minor
Currently, the CEP library only supports a Java API to specify complex event
patterns. In order to make it a bit less verbose for Scala users, it would be
nice to also add a Scala API for the CEP library.
A Scala API would also allow to pass Scala's anonymous functions as filter
conditions or as a select function, for example, or to use partial functions to
distinguish between different events.
Furthermore, the Scala API could be designed to feel a bit more like a DSL:
{code}
begin "start" where _.id >= 42 -> "middle_1" as classOf[Subclass] || "middle_2"
where _.name equals "foobar" -> "end" where x => x.id <= x.volume
{code}
