Class Summary

Class	Description
KafkaStreams	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.
KeyQueryMetadata	Represents all the metadata related to a key, where a particular key resides in a KafkaStreams application.
KeyValue<K,V>	A key-value pair defined for a single Kafka Streams record.
LagInfo	Encapsulates information about lag, at a store partition replica (active or standby).
StoreQueryParameters<T>	StoreQueryParameters allows you to pass a variety of parameters when fetching a store for interactive query.
StreamsBuilder	StreamsBuilder provide the high-level Kafka Streams DSL to specify a Kafka Streams topology.
StreamsConfig	Configuration for a KafkaStreams instance.
StreamsConfig.InternalConfig
TestInputTopic<K,V>	TestInputTopic is used to pipe records to topic in TopologyTestDriver.
TestOutputTopic<K,V>	TestOutputTopic is used to read records from a topic in TopologyTestDriver.
Topology	A logical representation of a ProcessorTopology.
TopologyTestDriver	This class makes it easier to write tests to verify the behavior of topologies created with Topology or StreamsBuilder.

Enum Summary

Enum	Description
KafkaStreams.State	Kafka Streams states are the possible state that a Kafka Streams instance can be in.
Topology.AutoOffsetReset	Sets the auto.offset.reset configuration when adding a source processor or when creating KStream or KTable via StreamsBuilder.
