> The reference manual says the following about memory requirements when streaming columns
from the network client - http://db.apache.org/derby/docs/10.7/ref/rrefjavsqlprst.html:
> > For applications using the client driver, if the stream is stored in a column of
a type other than LONG VARCHAR or LONG VARCHAR FOR BIT DATA, the entire stream must be able
to fit into memory at one time. Streams stored in LONG VARCHAR and LONG VARCHAR FOR BIT DATA
columns do not have this limitation.
> I believe this is not true any more. There was a lot of work to reduce the memory requirements
for LOBs in Derby 10.2 and Derby 10.3, and I think the specific problem referred to in this
section of the manual was fixed in DERBY-550/DERBY-1301.
