Record Components:

T - Pair<Mutation, Integer> pair of Mutations and associated rowlock ids .

@LimitedPrivate("Coprocesssor")
public class MiniBatchOperationInProgress<T>
extends Object

Wraps together the mutations which are applied as a batch to the region and their operation status and WALEdits.

Constructor Details

MiniBatchOperationInProgress

public MiniBatchOperationInProgress(T[] operations,
 OperationStatus[] retCodeDetails,
 WALEdit[] walEditsFromCoprocessors,
 int firstIndex,
 int lastIndexExclusive,
 int readyToWriteCount)

Method Details

size

public int size()

Returns The number of operations(Mutations) involved in this batch.

getOperation

public T getOperation(int index)

Returns The operation(Mutation) at the specified position.

setOperationStatus

public void setOperationStatus(int index,
 OperationStatus opStatus)

Sets the status code for the operation(Mutation) at the specified position. By setting this status, RegionObserver can make HRegion to skip Mutations.

getOperationStatus

public OperationStatus getOperationStatus(int index)

Returns Gets the status code for the operation(Mutation) at the specified position.

setWalEdit

public void setWalEdit(int index,
 WALEdit walEdit)

Sets the walEdit for the operation(Mutation) at the specified position.

getWalEdit

public WALEdit getWalEdit(int index)

Returns Gets the walEdit for the operation(Mutation) at the specified position.

getAbsoluteIndex

private int getAbsoluteIndex(int index)

addOperationsFromCP

public void addOperationsFromCP(int index,
 Mutation[] newOperations)

Add more Mutations corresponding to the Mutation at the given index to be committed atomically in the same batch. These mutations are applied to the WAL and applied to the memstore as well. The timestamp of the cells in the given Mutations MUST be obtained from the original mutation. Note: The durability from CP will be replaced by the durability of corresponding mutation. Note: Currently only supports Put and Delete operations.

Parameters:

index - the index that corresponds to the original mutation index in the batch

newOperations - the Mutations to add

getOperationsFromCoprocessors

public Mutation[] getOperationsFromCoprocessors(int index)

getReadyToWriteCount

public int getReadyToWriteCount()

getLastIndexExclusive

public int getLastIndexExclusive()

getCellCount

public int getCellCount()

addCellCount

public void addCellCount(int cellCount)

public int getNumOfPuts()

incrementNumOfPuts

public void incrementNumOfPuts()

getNumOfDeletes

public int getNumOfDeletes()

incrementNumOfDeletes

public void incrementNumOfDeletes()

getNumOfIncrements

public int getNumOfIncrements()

incrementNumOfIncrements

public void incrementNumOfIncrements()
