>
> With
> [KIP-813|https://cwiki.apache.org/confluence/display/KAFKA/KIP-813%3A+Shareable+State+Stores],
> new 'read-only state store' were introduced. The initial scope was to add
> builder.table() (with "source topic optimization") to the PAPI, and is now
> implemented on the Topology class:
> [Topology#addReadOnlyStateStore(_)|https://kafka.apache.org/38/javadoc/org/apache/kafka/streams/Topology.html#addReadOnlyStateStore(org.apache.kafka.streams.state.StoreBuilder,java.lang.String,org.apache.kafka.streams.processor.TimestampExtractor,org.apache.kafka.common.serialization.Deserializer,org.apache.kafka.common.serialization.Deserializer,java.lang.String,java.lang.String,org.apache.kafka.streams.processor.api.ProcessorSupplier)]
> h4. Proposed Changes
> Expose the new functionality via a new _public interface_ on
> {{{}org.apache.kafka.streams.StreamsBuilder{}}}.
> (a similar interface also exists for global state store ->
> [StreamsBuilder.addGlobalStore(_)|https://kafka.apache.org/38/javadoc/org/apache/kafka/streams/StreamsBuilder.html#addGlobalStore(org.apache.kafka.streams.state.StoreBuilder,java.lang.String,org.apache.kafka.streams.kstream.Consumed,org.apache.kafka.streams.processor.ProcessorSupplier])
