|---|---|
| ConstantInputDStream<T> |
An input stream that always returns the same RDD on each time step.
|
| DStream<T> |
A Discretized Stream (DStream), the basic abstraction in Spark Streaming, is a continuous
sequence of RDDs (of the same type) representing a continuous stream of data (see
org.apache.spark.rdd.RDD in the Spark core documentation for more details on RDDs).
|
| InputDStream<T> |
This is the abstract base class for all input streams.
|
| MapWithStateDStream<KeyType,ValueType,StateType,MappedType> |
DStream representing the stream of data generated by
mapWithState operation on a
pair DStream. |
| PairDStreamFunctions<K,V> |
Extra functions available on DStream of (key, value) pairs through an implicit conversion.
|
| ReceiverInputDStream<T> |
Abstract class for defining any
InputDStream
that has to start a receiver on worker nodes to receive external data. |
