* NdbBlob supports 3 styles of data access:
*
* - in prepare phase, NdbBlob methods getValue and setValue are used to
* prepare a read or write of a single blob value of known size
* prepare a read or write of a blob value of known size
*
* - in active phase, NdbBlob methods readData and writeData are used to
* read or write blob data of undetermined size
* - in prepare phase, setActiveHook is used to define a routine which
* is invoked as soon as the handle becomes active
*
* - in active phase, readData and writeData are used to read or write
* blob data of arbitrary size
*
* The styles can be applied in combination (in above order).
*
* Blob operations take effect at next transaction execute. In some
* cases NdbBlob is forced to do implicit executes. To avoid this,
* operate on complete blob parts.
*
* Use NdbConnection::executePendingBlobOps to flush your reads and
* writes. It avoids execute penalty if nothing is pending. It is not
* needed after execute (obviously) or after next scan result.
*
* NdbBlob methods return -1 on error and 0 on success, and use output
* parameters when necessary.
*
* Notes:
* - table and its blob part tables are not created atomically
* - blob data operations take effect at next transaction execute
* - NdbBlob may need to do implicit executes on the transaction
* - read and write of complete parts is much more efficient
* - scan must use the "new" interface NdbScanOperation
* - scan with blobs applies hold-read-lock (at minimum)
* - to update a blob in a read op requires exclusive tuple lock
* - update op in scan must do its own getBlobHandle
