Greetings,

Given that  the Cassandra server can host multiple client and  those
clients can open the same graph on the server simultaneously.  Basically
two updatable synchronized views on one data set.

Assume graph A is opened on client X and client Y and applications at X and
Y both register listeners on the graph.

If application at X deletes a triple should the listener at Y be notified?

I have been thinking about adding a queue based (JMS 1.1?) listener
implementation so that distributed system would be notified of changes from
remote systems.

The second question deals with reasoners.  If the reasoners are using the
distributed graph store then I don't think there is an issue so perhaps
this one goes away but.....

Reasoners do not like it  (don't respond to) data that is written into the
graph behind the scenes.  In a distributed environment does it make sense
to somehow utilize the graph listen messages (as noted above) to fire
update rules?

Are there other issues that I have missed?
