> {{StreamsBuilder#addGlobalStore}} is conceptually a 1:1 copy of {{Topology#addGlobalStore}}, that would follow DSL design principles though. Atm, {{StreamsBuilder#addGlobalStore}} does not follow provide a good user experience as it forces users to specify names for processor names – processor name are a Processor API detail should be hidden in the DSL. The current API is the following:
> {noformat}
> public synchronized StreamsBuilder addGlobalStore(final StoreBuilder storeBuilder,
> final String topic,
> final String sourceName,
> final Consumed consumed,
> final String processorName,
> final ProcessorSupplier stateUpdateSupplier)
> {noformat}
> We should remove the two parameters {{sourceName}} and {{processorName}}. To be backward compatible, the current method must be deprecated and a new method should be added with reduced number of parameters.
