NDB Cluster Configuration Files 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. Note In NDB API applications, you can control  BLOB  write batching with the setMaxPendingBlobReadBytes()  and  getMaxPendingBlobReadBytes() methods.

When using the  NDBCLUSTER  storage engine, this option specifies the management server that distributes cluster configuration data.
