Hi *,
I would like to know your opinion about using Cassandra to implement a
RBAC-like authentication authorization model. We have simplified the
central relationship of the general model (
http://en.wikipedia.org/wiki/Role-based_access_control) to:
user ---n:m--- role ---n:m--- resource
user ---n:m--- role ---n:m--- resource
I'm not sure what this means.
While some inconsistencies may be acceptable, resource ownership (i.e.
role=owner) must never ever be mixed up.
If you are working at a high enough Consistent Level there Cassandra will
provide consistent behaviour.
user ---n:m--- role ---n:m--- resource
It can work, but Cassandra is not RDBMS as you know, so RDBMS-ish data
modeling may not fit in production. (depends on your requirement on
performance. I'm not sure.)
In general you should better to desgin schema from your access pattern.
