Uses of KeyedStream in org.apache.flink.streaming.api.datastream

Methods in org.apache.flink.streaming.api.datastream that return KeyedStream

Modifier and Type	Method and Description
KeyedStream<T,org.apache.flink.api.java.tuple.Tuple>	DataStream.keyBy(int... fields) Deprecated. Use DataStream.keyBy(KeySelector).
<K> KeyedStream<T,K>	DataStream.keyBy(org.apache.flink.api.java.functions.KeySelector<T,K> key) It creates a new KeyedStream that uses the provided key for partitioning its operator states.
<K> KeyedStream<T,K>	DataStream.keyBy(org.apache.flink.api.java.functions.KeySelector<T,K> key, org.apache.flink.api.common.typeinfo.TypeInformation<K> keyType) It creates a new KeyedStream that uses the provided key with explicit type information for partitioning its operator states.
KeyedStream<T,org.apache.flink.api.java.tuple.Tuple>	DataStream.keyBy(String... fields) Deprecated. Use DataStream.keyBy(KeySelector).
static <T,K> KeyedStream<T,K>	DataStreamUtils.reinterpretAsKeyedStream(DataStream<T> stream, org.apache.flink.api.java.functions.KeySelector<T,K> keySelector) Reinterprets the given DataStream as a KeyedStream, which extracts keys with the given KeySelector.
static <T,K> KeyedStream<T,K>	DataStreamUtils.reinterpretAsKeyedStream(DataStream<T> stream, org.apache.flink.api.java.functions.KeySelector<T,K> keySelector, org.apache.flink.api.common.typeinfo.TypeInformation<K> typeInfo) Reinterprets the given DataStream as a KeyedStream, which extracts keys with the given KeySelector.

Methods in org.apache.flink.streaming.api.datastream with parameters of type KeyedStream

Modifier and Type	Method and Description
<T1> KeyedStream.IntervalJoin<T,T1,KEY>	KeyedStream.intervalJoin(KeyedStream<T1,KEY> otherStream) Join elements of this KeyedStream with elements of another KeyedStream over a time interval that can be specified with KeyedStream.IntervalJoin.between(Time, Time).
