MiniBatchOperationInProgress

public MiniBatchOperationInProgress(T[] operations,
                                    OperationStatus[] retCodeDetails,
                                    WALEdit[] walEditsFromCoprocessors,

                                    int readyToWriteCount)

Method Detail

size

public int size()

Returns:

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

getOperation

public T getOperation(int index)

n * @return 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. nn

getOperationStatus

public OperationStatus getOperationStatus(int index)

n * @return 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. nn

getWalEdit

public WALEdit getWalEdit(int index)

n * @return Gets the walEdit for the operation(Mutation) at the specified position.

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)
