Constructor Detail

SnapshotPartitionsQuickVerifyHandler

public SnapshotPartitionsQuickVerifyHandler(GridCacheSharedContext<?,?> cctx)

Parameters:

cctx - Shared context.

Method Detail

type

public SnapshotHandlerType type()

Snapshot handler type.

Specified by:

type in interface SnapshotHandler<Map<PartitionKeyV2,PartitionHashRecordV2>>

Overrides:

type in class SnapshotPartitionsVerifyHandler

invoke

public Map<PartitionKeyV2,PartitionHashRecordV2> invoke(SnapshotHandlerContext opCtx)
                                                       throws IgniteCheckedException

Local processing of a snapshot operation. Called on every node that contains snapshot data.

Specified by:

invoke in interface SnapshotHandler<Map<PartitionKeyV2,PartitionHashRecordV2>>

Overrides:

invoke in class SnapshotPartitionsVerifyHandler

Parameters:

opCtx - Snapshot handler context.

Returns:

Result of local processing. This result will be returned in SnapshotHandlerResult.data() method passed into SnapshotHandler.complete(String, Collection) handler method.

Throws:

IgniteCheckedException

complete

public void complete(String name,
                     Collection<SnapshotHandlerResult<Map<PartitionKeyV2,PartitionHashRecordV2>>> results)
              throws IgniteCheckedException

Processing the results of the SnapshotHandler.invoke(SnapshotHandlerContext) method received from all nodes. This method is called on coordinator node for SnapshotHandlerType.CREATE handler type and on the random node containing the snapshot data for SnapshotHandlerType.RESTORE.

Note: If this method fails, the entire cluster-wide snapshot operation will be aborted and the changes made by it will be rolled back.

Specified by:

complete in interface SnapshotHandler<Map<PartitionKeyV2,PartitionHashRecordV2>>

Overrides:

complete in class SnapshotPartitionsVerifyHandler

Parameters:

name - Snapshot name.

results - Results from all nodes.

Throws:

SnapshotWarningException - If a warning of snapshot operation occurred.

IgniteCheckedException

skipHash

protected boolean skipHash()

Provides flag of full hash calculation.

Overrides:

skipHash in class SnapshotPartitionsVerifyHandler

Returns:
