Class and Description
AllWindowedStream A AllWindowedStream represents a data stream where the stream of elements is split into windows based on a WindowAssigner.
AsyncDataStream.OutputMode Output mode for asynchronous operations.
BroadcastConnectedStream A BroadcastConnectedStream represents the result of connecting a keyed or non-keyed stream, with a BroadcastStream with broadcast state(s).
BroadcastStream A BroadcastStream is a stream with broadcast state(s).
CachedDataStream CachedDataStream represents a DataStream whose intermediate result will be cached at the first time when it is computed.
CoGroupedStreams CoGroupedStreams represents two DataStreams that have been co-grouped.
CoGroupedStreams.TaggedUnion Internal class for implementing tagged union co-group.
CoGroupedStreams.UnionSerializer TypeSerializer for CoGroupedStreams.TaggedUnion.
CoGroupedStreams.Where CoGrouped streams that have the key for one side defined.
CoGroupedStreams.Where.EqualTo A co-group operation that has KeySelectors defined for both inputs.
CoGroupedStreams.WithWindow A co-group operation that has KeySelectors defined for both inputs as well as a WindowAssigner.
ConnectedStreams ConnectedStreams represent two connected streams of (possibly) different data types.
CustomSinkOperatorUidHashes This class is responsible to hold operator Uid hashes from the common operators of the sink.
CustomSinkOperatorUidHashes.SinkOperatorUidHashesBuilder Builder to construct CustomSinkOperatorUidHashes.
DataStream A DataStream represents a stream of elements of the same type.
DataStream.Collector This class acts as an accessor to elements collected via DataStream.collectAsync(Collector).
DataStreamSink A Stream Sink.
DataStreamSource The DataStreamSource represents the starting point of a DataStream.
IterativeStream Deprecated. This method is deprecated since Flink 1.19. The only known use case of this Iteration API comes from Flink ML, which already has its own implementation of iteration and no longer uses this API. If there's any use cases other than Flink ML that needs iteration support, please reach out to dev@flink.apache.org and we can consider making the Flink ML iteration implementation a separate common library.
IterativeStream.ConnectedIterativeStreams Deprecated. This method is deprecated since Flink 1.19.

JoinedStreams JoinedStreams represents two DataStreams that have been joined.
JoinedStreams.Where Joined streams that have the key for one side defined.
JoinedStreams.Where.EqualTo A join operation that has KeySelectors defined for both inputs.
JoinedStreams.WithWindow A join operation that has KeySelectors defined for both inputs as well as a WindowAssigner.
KeyedStream A KeyedStream represents a DataStream on which operator state is partitioned by key using a provided KeySelector.
KeyedStream.IntervalJoin Perform a join over a time interval.
KeyedStream.IntervalJoined IntervalJoined is a container for two streams that have keys for both sides as well as the time boundaries over which elements should be joined.
PartitionWindowedStream PartitionWindowedStream represents a data stream that collects all records of each partition separately into a full window.
QueryableStateStream Deprecated. The Queryable State feature is deprecated since Flink 1.18, and will be removed in a future Flink major version.
SideOutputDataStream A SideOutputDataStream represents a DataStream that contains elements that are emitted from upstream into a side output with some tag.
SingleOutputStreamOperator SingleOutputStreamOperator represents a user defined transformation applied on a DataStream with one predefined output type.
WindowedStream A WindowedStream represents a data stream where elements are grouped by key, and for each key, the stream of elements is split into windows based on a WindowAssigner.
