Ted Ross created DISPATCH-477:
---------------------------------
Summary: Drop pre-settled under congestion
Key: DISPATCH-477
URL: https://issues.apache.org/jira/browse/DISPATCH-477
Project: Qpid Dispatch
Issue Type: New Feature
Components: Router Node
Reporter: Ted Ross
Assignee: Ted Ross
Fix For: 0.7.0
When a pre-settled (fire-and-forget) delivery is routed to a destination, and
that destination's undelivered FIFO is at or above its capacity (default 250),
pre-settled deliveries must be dropped to reduce congestion and prevent
unbounded memory consumption.
Once congestion is detected on a pre-settled delivery, all earlier pre-settled
deliveries on the same outgoing link shall be dropped and only the most recent
pre-settled delivery shall remain. Note that an outgoing link may contain a
mixture of pre-settled and unsettled deliveries.
