This option can be used to set the size (in bytes) for batching of BLOB  data reads in NDB Cluster applications. When this batch size is exceeded by the amount of BLOB  data to be read within the current transaction, any pending BLOB  read operations are immediately executed. 

The maximum value for this option is 4294967295; the default is 65536. Setting it to 0 has the effect of disabling BLOB  read batching.
