MySQL NDB Cluster API Developer Guide

2.3.30.27 NdbTransaction::setMaxPendingBlobWriteBytes()

Description.  Sets the batch size in bytes for BLOB write operations. When the volume of BLOB data to be written within a given transaction exceeds this amount, all of the transaction's pending BLOB write operations are executed.

Signature. 

void setMaxPendingBlobWriteBytes
    (
      Uint32 bytes
    )

Parameters.  The batch size, as the number of bytes. Using 0 causes BLOB write batching to be disabled, which is the default behavior (for backward compatibility).

Return value.  None.

Note

BLOB write batching can also be controlled in the mysql client and other MySQL client application using the MySQL Server's --ndb-blob-write-batch-bytes option and its associated MySQL Server system variables.
