Adds a global StateStore to the topology. Global stores should not be added to Processor, Transformer, or ValueTransformer (in contrast to regular stores).

It is not required to connect a global store to Processor, Transformer, or ValueTransformer; those have read-only access to all global stores by default.

Adds a state store to the underlying Topology. The store must still be "connected" to a Processor, Transformer, or ValueTransformer before it can be used.

It is required to connect state stores to Processor, Transformer, or ValueTransformer before they can be used.

Returns the Topology that represents the specified processing logic and accepts a Properties instance used to indicate whether to optimize topology or not.

Create a GlobalKTable from the specified topic. The resulting GlobalKTable will be materialized in a local KeyValueStore configured with the provided instance of Materialized. The serializers from the implicit Consumed instance will be used.

Create a GlobalKTable from the specified topic. The serializers from the implicit Consumed instance will be used. Input records with null key will be dropped.

Create a kstream.KStream from the specified topic pattern.

Create a kstream.KStream from the specified topics.

Create a kstream.KStream from the specified topic.

The implicit Consumed instance provides the values of auto.offset.reset strategy, TimestampExtractor, key and value deserializers etc. If the implicit is not found in scope, compiler error will result.

A convenient alternative is to have the necessary implicit serdes in scope, which will be implicitly converted to generate an instance of Consumed. @see ImplicitConversions.

// Brings all implicit conversions in scope
import ImplicitConversions._

// Bring implicit default serdes in scope
import Serdes._

val builder = new StreamsBuilder()

// stream function gets the implicit Consumed which is constructed automatically
// from the serdes through the implicits in ImplicitConversions#consumedFromSerde
val userClicksStream: KStream[String, Long] = builder.stream(userClicksTopic)
