Ken Giusti created DISPATCH-98:
----------------------------------
Summary: Refactor the handling of Message Annotations
Key: DISPATCH-98
URL: https://issues.apache.org/jira/browse/DISPATCH-98
Project: Qpid Dispatch
Issue Type: Improvement
Components: Router Node
Affects Versions: 0.3
Reporter: Ken Giusti
Priority: Minor
Fix For: 0.4
In order to facility DISPATCH-89, we need to modify the way the router updates
the router-specific fields in the Message Annotations section of a forwarded
message.
Currently, all the salient fields - trace, ingress, to-override, etc - are
updated all at once prior to forwarding. Let's break this up so fields may be
updated individually as needed. Specifically, for DISPATCH-89, the custom
forwarding code will need to update the to-override after the route lookup is
done. In addition, will need to set unique values for to-override for each
copy of the message that is created.
As an optimization, we should adopt a lazy approach to encoding these field
values: only build the final outgoing Message Annotation section as the message
is being sent out.
