Hi All,
Is there a concept of a session? I would like to log-in(authenticate) one
time into the Cassandra, and then subsequently access the Cassandra without
authenticating again.
Thanks,
Indika

Hi Aaron,
I read some articles about the Cassandra, and now understand a little bit
about trade-offs.
I feel the goal should be to optimize memory as well as performance. I have
to consider the number of column families, the columns per a family, the
number of rows, the memtable’s threshold, and
As the actual problem is mostly related to the number of CFs in the system
(may be number of the columns), I still believe that supporting exposing the
Cassandra ‘as-is’ to a tenant is doable and suitable though need some
fixes. That multi-tenancy model allows a tenant to use the programming
model

Hi all,
Would it be worth the capability of configuring the implementation of the
Cassandra.Iface?. I have to intercept the requests to the Cassandra server
without modifying the existing code (CassandraServer.java). So, the
server-side implementation of the Cassandra.Iface (CassandraServer) need
Hi All,
Shouldn't the existing method be changed to the following?
public boolean authorize(AuthenticatedUser user, List resource,
Permission permission); // checks the authority for a given user for a
given resource for a given permission
The existing method:
public EnumSet authorize(Authent
Thanks Eric for the clarification.

Hi All,
I observed the behavior indicated in the subject of this email even the
‘default User’ returned from authentication is null. Is this correct?
Thanks,
Indika
appreciate the suggestions for implementing the aforementioned idea
listed in the wiki.
Thanks,

Hi All,
Currently, there are two permissions - read and write, and there is no way
to know the current operation being performed such as add, update, etc. If
the operation is 'add', as the user is already logged into the system, I
would like to authorize the user for the resource going to add. I t
