+/**
+ * @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
