Class Summary

Class	Description
AbstractMemState<K,N,SV,S extends org.apache.flink.api.common.state.State,SD extends org.apache.flink.api.common.state.StateDescriptor<S,?>>	Base class for partitioned ListState implementations that are backed by a regular heap hash map.
AbstractMemStateSnapshot<K,N,SV,S extends org.apache.flink.api.common.state.State,SD extends org.apache.flink.api.common.state.StateDescriptor<S,?>>	A snapshot of a MemValueState for a checkpoint.
ByteStreamStateHandle	A state handle that contains stream state in a byte array.
MemFoldingState<K,N,T,ACC>	Heap-backed partitioned FoldingState that is snapshotted into a serialized memory copy.
MemFoldingState.Snapshot<K,N,T,ACC>
MemListState<K,N,V>	Heap-backed partitioned ListState that is snapshotted into a serialized memory copy.
MemListState.Snapshot<K,N,V>
MemoryStateBackend	A AbstractStateBackend that stores all its data and checkpoints in memory and has no capabilities to spill to disk.
MemoryStateBackend.MemoryCheckpointOutputStream	A CheckpointStateOutputStream that writes into a byte array.
MemReducingState<K,N,V>	Heap-backed partitioned ReducingState that is snapshotted into a serialized memory copy.
MemReducingState.Snapshot<K,N,V>
MemValueState<K,N,V>	Heap-backed key/value state that is snapshotted into a serialized memory copy.
MemValueState.Snapshot<K,N,V>
SerializedStateHandle<T extends Serializable>	A state handle that represents its state in serialized form as bytes.
