> The snapshot restore may hang when some of the cache group partitions have not been physically created (for example, there is not enough data in the cache).
> Reproducer
> {code:java}
> public class IgniteClusterSnapshotRestoreEmptyPartsTest extends IgniteClusterSnapshotRestoreBaseTest {
>     @Test
>     public void testRestoreWithEmptyPartition() throws Exception {
>         // Cache with 1024 partitions.
>         CacheConfiguration<Integer, Object> cacheCfg1 = new CacheConfiguration<>(CACHE1);
>         // Add only 10 keys (only 10 partitions will be created on the disk).
>         IgniteEx ignite = startGridsWithCache(1, 10, Integer::new, cacheCfg1);
>         // Snapshot contains only 10 (out of 1024 "affinity" partitions).
>         ignite.snapshot().createSnapshot(SNAPSHOT_NAME).get(TIMEOUT);
>         ignite.cache(CACHE1).destroy();
>         // The restore operation hangs during the "preload" phase.
>         ignite.snapshot().restoreSnapshot(SNAPSHOT_NAME, null).get(TIMEOUT);
>     }
> }
> {code}
