ClassDescription
KafkaClientSuppliercan be used to provide custom Kafka clients to aKafkaStreamsinstance.A Kafka client that allows for performing continuous computation on input coming from one or more input topics and sends output to zero, one, or more output topics.Class that handles options passed in case ofKafkaStreamsinstance scale downKafka Streams states are the possible state that a Kafka Streams instance can be in.Listen toKafkaStreams.Statechange events.Represents all the metadata related to a key, where a particular key resides in aKafkaStreamsapplication.KeyValue<K,V> A key-value pair defined for a single Kafka Streams record.Encapsulates information about lag, at a store partition replica (active or standby).StoreQueryParametersallows you to pass a variety of parameters when fetching a store for interactive query.StreamsBuilderprovide the high-level Kafka Streams DSL to specify a Kafka Streams topology.Configuration for aKafkaStreamsinstance.Metadata of a Kafka Streams client.The Kafka Streams metrics interface for adding metric sensors and collecting metric values.Metadata of a task.TestInputTopic<K,V> TestInputTopicis used to pipe records to topic inTopologyTestDriver.TestOutputTopic<K,V> TestOutputTopicis used to read records from a topic inTopologyTestDriver.Metadata of a stream thread.A logical representation of aProcessorTopology.Sets theauto.offset.resetconfiguration whenadding a source processoror when creatingKStreamorKTableviaStreamsBuilder.Streams configs that apply at the topology level.A meta representation of atopology.Represents aglobal store.A node of a topology.A processor node of a topology.A sink node of a topology.A source node of a topology.A connected sub-graph of aTopology.This class makes it easier to write tests to verify the behavior of topologies created withTopologyorStreamsBuilder.
