This could be perfectly done when you are reading the data from file

over the InputStream, of course.
AFAIK current JDBC drivers (except oracle?) are not able to stream BLOBs
without loading it completely into memory.
Another problem could be transferring a big message (20MB) over a slow
dialup connection, which would block one DB connection for a long time.
So with JDBC there is probably no way to avoid the byte array for the
body.
this is one area where hybrid file-database data stores (such as JCRs)
may well have performance benefits over pure database implementations
"All that glitters is not gold"
Does JCR spec support streaming objects while writing to the repository?
Do current JCR implementations correctly support streaming (without
loading in memory) of data?
I remember I had big issues with streams and JackRabbit: maybe it is an
hole in the spec, or maybe a JackRabbit issue, or maybe I've not been
smart enough, but when I read this streaming thread I recall that I
should not be so happy to put +1 on JCR in later discussions ;-)
