Hello, I was curious when is the Orion team
planning on releasing a version that will support the local interfaces that are
part of the (proposed) EJB 2 spec. Or will you wait for the spec to become
finalized.
In lieu of that:
I was scouring through the orion mail list and saw
a discussion about whether Orion uses a different mechanism when a client that
is co-located in the same VM as an ejb invokes a remote interface method as
opposed to when the client is truly "remote" (in the sense that it's in another
VM or on another physical machine).
I didn't see a clear response to that
question.
My interest, of course, is in
performance.
RMI has 2 performance hits associated with
it:
1. If from another machine, obviously the
network latency involved
2. The serialization/deserialization
(marshalling/unmarshalling if you prefer) of method arguments and return
values.
Obviously, it is this very issue that the EJB 2
spec is addressing with the advent of local interfaces. But I need to
implement my system now, and it has large implications for how I architect the
system, i.e. what the current release of Orion does.
I'd appreciate any help from the Orion team.
Thanks.
P.S. Congratulations on helping Oracle see
the light. |
