> Key: KAFKA-6138
> URL: https://issues.apache.org/jira/browse/KAFKA-6138
> Project: Kafka
> Issue Type: Bug
> Components: streams
> Affects Versions: 1.0.0
> Reporter: Matthias J. Sax
> Assignee: Panuwat Anawatmongkhon
> Priority: Major
> Labels: beginner, kip, newbie
>
> {{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.
