/**
* @class NdbBlob
* @brief Blob handle
*
* Blob data is stored in 2 places:
*
* - "header" and "inline bytes" stored in the blob attribute
* - "blob parts" stored in a separate table NDB$BLOB_<t>_<v>_<c>
*
* Inline and part sizes can be set via NdbDictionary::Column methods
* when the table is created.
*
* NdbBlob is a blob handle. To access blob data, the handle must be
* created using NdbOperation::getBlobHandle in operation prepare phase.
* The handle has following states:
*
* - prepared: before the operation is executed
* - active: after execute or next result but before transaction commit
* - closed: after transaction commit
* - invalid: after rollback or transaction close
*
* NdbBlob supports 2 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
*
* - in active phase, NdbBlob methods readData and writeData are used to
* read or write blob data of undetermined size
*
* 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
* - delete creates implicit, not-accessible blob handles
* - NdbOperation::writeTuple does not support blobs
* - there is no support for an asynchronous interface
*
* Bugs / limitations:
* - scan must use exclusive locking for now
*
* Todo:
* - add scan method hold-read-lock-until-next + return-keyinfo
* - better check of keyinfo length when setting keys
* - better check of allowed blob op vs locking mode
