构造器详细资料

BatchWriteRowRequest

public BatchWriteRowRequest()

方法详细资料

getOperationName

public String getOperationName()

addRowChange

public void addRowChange(RowChange rowChange)

Add write operation parameters for a specific table.

参数:

rowChange - Parameters for a write operation. The operation type can be Put, Update, or Delete. If Txn is used, each BatchWriteRow is only allowed for a single table.

getRowChange

public RowChange getRowChange(String tableName,
                              int index)

Returns the parameters for a single write operation based on the table name and index. The multi-row results returned in BatchWriteRowResult allow partial success and partial failure. The returned results are organized by table, and the order of rows within the table corresponds one-to-one with the order in BatchWriteRowRequest. If the user needs to retry some failed rows from BatchWriteRowResult, they can look up the request parameters from BatchWriteRowRequest using the table name of the failed row's table and its index in the returned result list.

参数:

tableName - the name of the table

index - the index of this row in the parameter list

返回:

parameters for a single write operation

getRowChange

public Map<String,List<RowChange>> getRowChange()

Get the operation parameters for all tables.

返回:

The operation parameters for all tables.

createRequestForRetry

public BatchWriteRowRequest createRequestForRetry(List<BatchWriteRowResponse.RowResult> failedRows)

Based on the returned result of the request, extract the rows that failed to execute and reconstruct a new request.

参数:

failedRows - Rows that failed during the write operation

返回:

A new request for retry

isEmpty

public boolean isEmpty()

getRowsCount

public int getRowsCount()

Get the total number of rows included in this BatchWriteRow request.

返回:

The total number of rows

isAtomicSet

public boolean isAtomicSet()

Whether the batch atomic write option is set.

返回:

Whether the batch atomic write option is set

setAtomic

public void setAtomic(boolean atomic)

Set whether to use batch atomic writes. If batch atomic write is enabled, you must ensure that the primary keys for writes to the same table are identical; otherwise, the write will fail.

参数:

atomic - Whether to use batch atomic writes

isAtomic

public boolean isAtomic()

Check if it is a batch atomic write.

返回:

whether it is a batch atomic write
