[SR-Users] Best practise for limiting concurrent calls across a cluster

[jay binks]

Im currently using cassandra with kamailio I need something thats highly
available and partition tolerant, consistency is a secondary requirement
for most of the data.

Im really not sure that restful web services are the right way here, that
seems like a LOT of overhead at high cps.

Sorry I forgot to add, that this is for a provider network, not a corporate
 / pbx implementation.
I need to be able to handle hundreds / thousands of invites per second,
with minimal latency.
