Public Interfaces
KStream.process
Proposed Changes
We want to make sure that we always have a serde for all Materialized, Serialized, Joined, Consumed and Produced.
For that we can make use of the implicit parameters in Scala.
Public Interfaces
Add of the following:
org.apache.kafka.streams.scala.kstream.Materialized
org.apache.kafka.streams.scala.kstream.Serialized
org.apache.kafka.streams.scala.kstream.Joined
org.apache.kafka.streams.scala.kstream.Consumed
org.apache.kafka.streams.scala.kstream.Produced
Proposed Changes
Add of helper functions to create Materialized, Serialized, Joined, Consumed and Produced with serdes implicitly given so that we are sure to not miss any.def process(processorSupplier: => Processor[K, V], stateStoreNames: String*)
Compatibility, Deprecation, and Migration Plan
Overload and deprecate, then remove the deprecated.
Rejected Alternatives
If there are alternative ways of accomplishing the same thing, what were they? The purpose of this section is to motivate why the design is the way it is and not some other way.NA
