Package com.linkedin.venice.pushmonitor

Class LeakedPushStatusCleanUpService

java.lang.Object

com.linkedin.venice.service.AbstractVeniceService

com.linkedin.venice.pushmonitor.LeakedPushStatusCleanUpService

All Implemented Interfaces:

Closeable, AutoCloseable

public class LeakedPushStatusCleanUpService
extends AbstractVeniceService

Reclaims push statuses that servers may write after asynchronous push cancellation and controller cleanup. Drops leaked Helix resources before removing residual push-status ZNodes on a later sweep. Runs with HelixVeniceClusterResources after metadata initialization and stops before repository teardown. The shared lock manager fences eligibility and deletion against store recreation and repository clearing.
