Hi,

The real problem is not in a place where h2 client stores temp blobs
but in the fact that it stores blobs to temp files at all. I think it
should not do this. It seems that it does this on each row fetch but
this is incorect since even if you have selected some result set
conatining blobs you are not necessarily will access this blobs but
they are all downloaded to the client machine. This can be ok if your
network is fast enough, blobs are not so big and you do not fetch too
many rows but if this is not the case you will have performance
problems. Also the write access problems you mention. So the right way
to fix this all is to get rid of temp blob files on client so that
result set will contain only some kind of links to remote blobs
instead of whole blob data.

regards,
S.Vladykin
