Dear all,

is something like a LastUniqueKeySubscriptionRecoveryPolicy available or in
the making? Possibly with some means to identify as well a final deletion
message via a query syntax similar to the
QueryBasedSubscriptionRecoveryPolicy? Or alternatively as an addendum to the
TimedSubscriptionRecoveryPolicy?

I'm asking because this is an important feature of DDS, and we are currently
comparing DDS and ActiveMQ for potential future use in Air Traffic
Managements applications. 

We have for instance track and flightplan object producers and consumers,
and whilst tracks are updated every 5 seconds, flightplans can linger in the
system for some time after initial creation without being updated, and a
consumer must upon restart be able to recover all the latest flightplan
messages for every individual flight ...

Sorry for posting this earlier in ActiveMQ-User, but there nobody replied to
my question within reasonable time ...

Kind regards,
Sebastian
