Enum Constant Summary

AtomicUpdate
Operation responsible for the atomic update of the index partition view as part of any of the asynchronous overflow tasks

ChooseView
Operation responsible for deciding how many of the sources in the view will be used for an incremental build operation.

CopyHistory
Deprecated. by MoveTask

ReceiveIndexPartition
The overall operation submitted to the target data service during a MOVE in which it receives the data for the source index partition and registers the target index partition.

ReceiveIndexSegment
The operation in which an IndexSegmentStore file is received by the target data service as part of a MOVE operation.

RegisterIndex
Registering a new index partition.

SendIndexSegment
Deprecated. by MoveTask

Total
Corresponds to the total overflow task for an index partition.

Method Summary

Enum Constant Detail

Total

public static final OverflowSubtaskEnum Total

Corresponds to the total overflow task for an index partition.

AtomicUpdate

public static final OverflowSubtaskEnum AtomicUpdate

Operation responsible for the atomic update of the index partition view as part of any of the asynchronous overflow tasks

OverflowActionEnum

ChooseView

public static final OverflowSubtaskEnum ChooseView

Operation responsible for deciding how many of the sources in the view will be used for an incremental build operation. When all sources are accepted, the build will actually be a compacting merge and deleted tuples will be purged from the index partition.

CopyHistory

public static final OverflowSubtaskEnum CopyHistory

Deprecated. by MoveTask

Copying historical data from the old journal.

RegisterIndex

public static final OverflowSubtaskEnum RegisterIndex

Registering a new index partition.

SendIndexSegment

public static final OverflowSubtaskEnum SendIndexSegment

Deprecated. by MoveTask

Operation copying an IndexSegment using the ResourceService.

ReceiveIndexPartition

public static final OverflowSubtaskEnum ReceiveIndexPartition

The overall operation submitted to the target data service during a MOVE in which it receives the data for the source index partition and registers the target index partition.

ReceiveIndexSegment

public static final OverflowSubtaskEnum ReceiveIndexSegment

The operation in which an IndexSegmentStore file is received by the target data service as part of a MOVE operation.

Method Detail

values

public static OverflowSubtaskEnum[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (OverflowSubtaskEnum c : OverflowSubtaskEnum.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static OverflowSubtaskEnum valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
