----------------------------------------

Hello Tomohito,

I see you are assigned to this issue. I'm working on DERBY-1417, and was wondering if you
could post a brief description of the changes to the client "API" you are planning to do as
part of this issue. After having had a very brief look at the callstack on the client  for
a setClob call, it seems the length parameter is required all over the place...
Do you plan to extend the current methods or provide new ones for streaming of lengthless
streams?

At the moment, the lower-level methods on the client side relies on the LOB.length() method,
and we will need changes in both the am and the net package. I fear this new feature will
require quite a lot of work!

I will put the client side work of DERBY-1417 on-hold for a while. Let me know if there is
anything I can do to help you out.

> JDBC 4.0 introduced new methods which take parameters for object to be sent to sever
without length information.
> For those methods, Layer B streaming is best way to implement sending object to server.
> This issue is representation of DERBY-1417 in Network Client.
