Description:
Follow up on bug #15089, we need the ability to load a subset of a BLOB into memory. BLOBs are meant to be used for large data, we don't want to load the entire thing into memory every time.

How to repeat:
Use java.sql.Blob.getBytes() to retrieve the 10 bytes in the middle of a 1GB file. Memory usage should be some small multiple of 10 bytes.

Thank you for the feature request.
