Замечания
The IDTSBLOBObject100 provides support for reading and writing bytes in a binary large object (BLOB). The bytes added to the object are stored in memory until the SpoolThreshold property is reached, and then are written to a temporary file.
Managed component developers do not use this object but instead use the BlobColumn class.
