org.apache.flink.runtime.state.KeyGroupedInternalPriorityQueue

使用KeyGroupedInternalPriorityQueue的程序包

程序包	说明
org.apache.flink.runtime.state
org.apache.flink.runtime.state.heap	This package contains the classes for key/value state backends that store the state on the JVM heap as objects.

org.apache.flink.runtime.state中KeyGroupedInternalPriorityQueue的使用

返回KeyGroupedInternalPriorityQueue的org.apache.flink.runtime.state中的方法

限定符和类型	方法和说明
<T extends HeapPriorityQueueElement & PriorityComparable<? super T> & Keyed<?>> KeyGroupedInternalPriorityQueue<T>	PriorityQueueSetFactory.create(String stateName, org.apache.flink.api.common.typeutils.TypeSerializer<T> byteOrderedElementSerializer) Creates a KeyGroupedInternalPriorityQueue.
<T extends HeapPriorityQueueElement & PriorityComparable<? super T> & Keyed<?>> KeyGroupedInternalPriorityQueue<T>	HeapPriorityQueuesManager.createOrUpdate(String stateName, org.apache.flink.api.common.typeutils.TypeSerializer<T> byteOrderedElementSerializer)

org.apache.flink.runtime.state.heap中KeyGroupedInternalPriorityQueue的使用

实现KeyGroupedInternalPriorityQueue的org.apache.flink.runtime.state.heap中的类

限定符和类型	类和说明
class	HeapPriorityQueueSet<T extends HeapPriorityQueueElement> A heap-based priority queue with set semantics, based on HeapPriorityQueue.
class	KeyGroupPartitionedPriorityQueue<T,PQ extends InternalPriorityQueue<T> & HeapPriorityQueueElement> This implementation of InternalPriorityQueue is internally partitioned into sub-queues per key-group and essentially works as a heap-of-heaps.
