Class AsyncTimelineServerBasedDetectionStrategy

java.lang.Object

org.apache.hudi.common.conflict.detection.TimelineServerBasedDetectionStrategy

org.apache.hudi.timeline.service.handlers.marker.AsyncTimelineServerBasedDetectionStrategy

All Implemented Interfaces:

EarlyConflictDetectionStrategy

public class AsyncTimelineServerBasedDetectionStrategy
extends TimelineServerBasedDetectionStrategy

This abstract strategy is used for writers using timeline-server-based markers, trying to do early conflict detection by asynchronously and periodically checking write conflict among multiple writers based on the timeline-server-based markers.
