> Project: Ignite
> Issue Type: Improvement
> Reporter: Pavel Pereslegin
> Assignee: Pavel Pereslegin
> Priority: Major
> Labels: iep-43, ise
> Fix For: 2.12

> Add JMX command to restore a cache group from the snapshot.
> Suggested methods
> {code:java}
> @MXBeanDescription("Restore cluster-wide snapshot.")
> public void restoreSnapshot(
> @MXBeanParameter(name = "snpName", description = "Snapshot name.")
> String name,
> @MXBeanParameter(name = "cacheGroupNames", description = "Optional
> comma-separated list of cache group names.") String cacheGroupNames);
> @MXBeanDescription("Cancel previously started snapshot restore
> operation.")
> public void cancelSnapshotRestore(@MXBeanParameter(name = "snpName",
> description = "Snapshot name.") String name);
> {code}
> Since the automatic snapshot restore operation can take a long time, we must
> be able to track its progress using metrics.
> Suggested metrics:
> {noformat}
> start time
> partitions (processed/total)
> bytes (processed/total)
> end time
> {noformat}
>
> Suggested status command output.
