org.apache.flink.runtime.state.heap使用的org.apache.flink.runtime.state.heap中的类

类和说明
AbstractHeapPriorityQueue Abstract base class for heap (object array) based implementations of priority queues, with support for fast deletes via HeapPriorityQueueElement.
AbstractHeapState Base class for partitioned State implementations that are backed by a regular heap hash map.
CopyOnWriteStateMap Implementation of Flink's in-memory state maps with copy-on-write support.
CopyOnWriteStateMapSnapshot This class represents the snapshot of a CopyOnWriteStateMap.
CopyOnWriteStateTableSnapshot This class represents the snapshot of a CopyOnWriteStateTable and has a role in operator state checkpointing.
HeapKeyedStateBackend A AbstractKeyedStateBackend that keeps state on the Java Heap and will serialize state to streams provided by a CheckpointStreamFactory upon checkpointing.
HeapPriorityQueue Basic heap-based priority queue for HeapPriorityQueueElement objects.
HeapPriorityQueueElement Interface for objects that can be managed by a HeapPriorityQueue.
HeapPriorityQueueSet A heap-based priority queue with set semantics, based on HeapPriorityQueue.
HeapPriorityQueueSetFactory Factory for HeapPriorityQueueSet.
HeapPriorityQueueSnapshotRestoreWrapper This wrapper combines a HeapPriorityQueue with backend meta data.
HeapPriorityQueueStateSnapshot This class represents the snapshot of an HeapPriorityQueueSet.
InternalKeyContext This interface is the current context of a keyed state.
KeyGroupPartitionedPriorityQueue.PartitionQueueSetFactory Factory that produces the sub-queues that represent the partitions of a KeyGroupPartitionedPriorityQueue.
StateMap Base class for state maps.
StateMapSnapshot Base class for snapshots of a StateMap.
StateTable Base class for state tables.
