I don't think so. Assuming drivers properly implement getBytes(pos, len)/setBytes(pos, data) such that they only transfer the requested/supplied number of bytes from the database then it is OK. I only transfer the amount requested by the caller or size of the buffer held by the stream. I have done some tests and can transfer 128MB in and out of the DB (in 1MB chunks) without blowing a 64MB stack (MySQL did struggle to process it). I have run into an interesting issue with MySQL (which may negate all I have said above) that you can't store a blob larger the max_allowed_packet setting. You don't get an exception you just end up with a NULL in the database. I am going to raise this as an issue with MySQL. Its possible we may need 2 implementations one for DBs (like MySQL) where getBytes/setBytes is required and one for DBs which getBinaryStream is more efficient. Regards, Mike.
