java.lang.Object

org.apache.flink.runtime.dispatcher.FileExecutionGraphInfoStore

所有已实现的接口:

Closeable, AutoCloseable, ExecutionGraphInfoStore

public class FileExecutionGraphInfoStore
extends Object
implements ExecutionGraphInfoStore

Store for ExecutionGraphInfo instances. The store writes the archived execution graph information to disk and keeps the most recently used execution graphs in a memory cache for faster serving. Moreover, the stored execution graphs are periodically cleaned up.
