Class Summary

Class	Description
AbstractFileStateHandle	Base class for state that is stored in a file.
AbstractFsState<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.
AbstractFsStateSnapshot<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 heap key/value state stored in a file.
FileSerializableStateHandle<T extends Serializable>	A state handle that points to state stored in a file via Java Serialization.
FileStreamStateHandle	A state handle that points to state in a file system, accessible as an input stream.
FsFoldingState<K,N,T,ACC>	Heap-backed partitioned FoldingState that is snapshotted into files.
FsFoldingState.Snapshot<K,N,T,ACC>
FsListState<K,N,V>	Heap-backed partitioned ListState that is snapshotted into files.
FsListState.Snapshot<K,N,V>
FsReducingState<K,N,V>	Heap-backed partitioned ReducingState that is snapshotted into files.
FsReducingState.Snapshot<K,N,V>
FsStateBackend	The file state backend is a state backend that stores the state of streaming jobs in a file system.
FsStateBackend.FsCheckpointStateOutputStream	A CheckpointStateOutputStream that writes into a file and returns the path to that file upon closing.
FsStateBackendFactory	A factory that creates an FsStateBackend from a configuration.
FsValueState<K,N,V>	Heap-backed partitioned ValueState that is snapshotted into files.
FsValueState.Snapshot<K,N,V>
