Parameters:

rqId - Unique request id.

snpName - Snapshot name.

consId - Consistent id of a node to which this metadata relates.

folderName - Directory name which stores the data files.

pageSize - Page size of stored snapshot data.

grpIds - The list of cache groups ids which were included into snapshot.

bltNodes - The set of affected by snapshot baseline nodes.

snpRecPtr - WAL pointer to ClusterSnapshotRecord if exists.

masterKeyDigest - Master key digest for encrypted caches.

onlyPrimary - If true snapshot only primary copies of partitions.

Method Detail

requestId

public UUID requestId()

Returns:

Unique snapshot request id.

snapshotName

public String snapshotName()

Returns:

Snapshot name.

consistentId

public String consistentId()

Returns:

Consistent id of a node to which this metadata relates.

folderName

public String folderName()

Returns:

Directory name which stores the data files.

pageSize

public int pageSize()

Returns:

Page size of stored snapshot data.

cacheGroupIds

public List<Integer> cacheGroupIds()

Returns:

The list of cache group IDs which were included into the snapshot globally.

baselineNodes

public Set<String> baselineNodes()

Returns:

The set of affected by snapshot baseline nodes.

partitions

public Map<Integer,Set<Integer>> partitions()

Returns:

Map of cache group partitions from which snapshot has been taken on the local node (which is actually saved on the local node because some of them may be skipped due to cache node filter).

isGroupWithCompresion

public boolean isGroupWithCompresion(int grpId)

hasCompressedGroups

public boolean hasCompressedGroups()

snapshotRecordPointer

@Nullable
public @Nullable WALPointer snapshotRecordPointer()

Returns:

WAL pointer to ClusterSnapshotRecord if exists.

onlyPrimary

public boolean onlyPrimary()

Returns:

If true snapshot only primary copies of partitions.

sameSnapshot

public boolean sameSnapshot(SnapshotMetadata compare)

Parameters:

compare - Snapshot metadata to compare.

Returns:

true if given metadata belongs to the same snapshot.

masterKeyDigest

public byte[] masterKeyDigest()

Returns:

Master key digest for encrypted caches.

warnings

public void warnings(List<String> warnings)

Parameters:

warnings - Snapshot creation warnings.

warnings

public List<String> warnings()

Returns:

Snapshot creation warnings.

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

public String toString()

Overrides:

toString in class Object
