Optimized Storage Stream for reduced BLOB size
All clipboard pages are serialized and are stored in BLOB columns named pzPVStream in the Pega 7 database. The Storage Stream (byte stream) that is stored in these BLOB columns has been optimized to make the BLOB values smaller, and to also make the encoding and reading of these values faster when opening and saving objects.
This update was completed by reducing redundancies in the stored data, redesigning the data structure to be more space efficient, and by selectively encoding only parts of the stream, instead of encoding the entire stream on each read.
