hi all,
i am just trying to find out if shoal would be a good fitting solution to my
problem.
architecture:
sun java appserver (glassfish 2.2)
10 appservers each has 20 EAR files deployed
each ear file should know a hasmap of blacklisted IP adresses (~100
addresses)
5 appservers on server 1 seperated from 5 appservers on server 2 via WAN
(low latency)
goal:
every ear file should be able to maintain a central black list where a list
of bad IP addresses is kept.
is shoal capeable of managing such distributed state? if yes which point to
start first whats the best entrypoint for me?
is there a very easy way to keep the hashmap on each ear file with the same
information ?
if yes what happens when wan goes down and ear 1 on server 1 adds an entry
will ear 2 on server 1 see this?
what is about the hashmaps on server 2 ? will the stay the same when network
WAN goes down and server 2 does not see server 1 anymore? (split brain?)
what happens if wan goes up again and server 1 discovers server 2 again?
is there a central place where such things are documented in shoal?
