[cas-user] no sql database support for storing ticket session
Do we know if we can use no sql dbs like Cassandra to store sessions in CAS? Any examples or wikis?

Re: [cas-user] no sql database support for storing ticket session
Hi. Everything is possible. In order to use any particular nosql store for ticket registry, one would need to have a particular implementation (written in code). I am personally not aware of an existing Cassandra Impl., but here is an example of Riak impl (Riak - is another nosql store): https://github.com/justinholmes/riakbackedcas/blob/master/cas-overlay-server-demo/src/main/java/uk/co/nascency/riakbackedcas/registry/RiakBackedTicketRegistry.java Cheers, Dmitriy.

Re: [cas-user] no sql database support for storing ticket session
I am curious, what would be the reason you'd choose a no sql database to store tickets?

Re: [cas-user] no sql database support for storing ticket session
Since NoSQL is a kind of catch-all term for any kind of data store that isn't a RDBMS, it may be hard to generalize. If you look at some of the more popular present-day NoSQL solutions, many of them seem to aim at prioritizing Availability and Partition Tolerance over Consistency (from the CAP theorem [1]). For the CAS ticket store, this doesn't seem to be a terrible idea. You need to be able to store tickets associated with an identity. CAS basically needs a key-value store in this regard. The characteristics of that store will likely need to be dictated in part by the environment in which a particular CAS operates.

Re: [cas-user] no sql database support for storing ticket session
Thanks for the reply. We are currently using Cassandra for our infra ( for scale and distributed reasons) and we would like to leverage the same for CAS too..

Re: [cas-user] no sql database support for storing ticket session
And so in this case, as I mentioned in my previous email, you would actually need to implement the TicketRegistry API in CAS for the Cassandra DB (as I’m not aware of any of the existing implementations).
