Class BackupTTLTask

java.lang.Object

com.netflix.priam.scheduler.Task

com.netflix.priam.backupv2.BackupTTLTask

All Implemented Interfaces:

org.quartz.Job

public class BackupTTLTask
extends Task

This class is used to TTL or delete the SSTable components from the backups after they are not referenced in the backups for more than IConfiguration.getBackupRetentionDays(). This operation is executed on CRON and is configured via IBackupRestoreConfig.getBackupTTLMonitorPeriodInSec().

To TTL the SSTable components we refer to the first manifest file on the remote file system after the TTL period. Any sstable components referenced in that manifest file should not be deleted. Any other sstable components (files) on remote file system before the TTL period can be safely deleted. Created by aagrawal on 11/26/18.
