------------------------------------------------------------------
hey [~mjsax] and [~vvcephei] it seems like this got abandoned. I assigned it
to myself and am working on a KIP. It's been 6 years; is this something we
still want?
For context, I'm a relatively new contributor but have already drafted a KIP
for KAFKA-20230 (waiting for my wiki id to be assigned before I post), and am
spun up on the Topology class.
Seems like this mainly involves coding new builder argument classes and
refactoring existing code while maintaining backwards compatibility. I'll
mention the exact new classes I'm planning to implement in my KIP when I have
it ready. I'm aiming to have it the KIP out within the next 2-3 weeks. I'm
hoping everyone is okay with this?

> During code review for KIP-478, I got this feedback from [~bbejeck] .
> In Topology, we have methods like this:
> {code:java}
> public synchronized <KIn, VIn> Topology addGlobalStore(
> final StoreBuilder<?> storeBuilder,
> final String sourceName,
> final TimestampExtractor timestampExtractor,
> final Deserializer<KIn> keyDeserializer,
> final Deserializer<VIn> valueDeserializer,
> final String topic,
> final String processorName,
> final ProcessorSupplier<KIn, VIn, Void, Void> stateUpdateSupplier){code}
> It would probably be better UX to preset a builder interface like:
> {code:java}
> public synchronized <KIn, VIn> Topology addGlobalStore(
> AddGlobalStoreParameters.fromStoreBuilder(storeBuiler)
> .withSourceName(sourceName)
> .withSourceTopic(topic)
> .withTimestampExtractor(timestampExtractor)
> .withKeyDeserializer(keyDeserializer)
> .withValueDeserializer(valueDeserializer)
> .withProcessorName(processorName)
> .withStateUpdateSupplier(stateUpdateSupplier)
> ){code}
>
> Note: new API design proposals should take into account the proposed grammar:
