okay, so what should a workable VPS configuration to start with & minimum
how many nodes to start with(2 ok?) ? Seriously I cannot afford the
tensions of colocation setup. My hosting provider provides SSD drives with
KVM virtualization.
Hey Brandon,
1. ) Is it devloped to the level in order to support all the
necessary features to take full advantage of Cassandra?
2. ) Is it used in production by anyone ?
3. ) What are its limitations?
Thanks.

I am not sure but I guess because all the rows of certain time range will go
to just one node & will not be evenly distributed because the timeUUID will
not be random but sequential according to time... I am not sure anyways...

Hey Tyler,
Is this limitation of supercolumns going to be removed anytime sooner ?

The fact that subcolumns inside the supercolumns aren't indexed
currently may suck here, whenever a small no (10-20 ) of subcolumns
need to be retreived from a large list of subcolumns of a supercolumn
like MyPostsIdKeysList.

This means that nodes in cassandra cluster contain data that has been
sharded onto serveral nodes as well as this sharded data may be
replicated further across several nodes ? So cassandra storage
utilizes both sharded as well as replication for load balancing? Is
this correct ?

What is the meaning of eventual consistency in Cassandra when nodes in
a single cluster do not mantain the copies of same data but rather
data is distributed among nodes. Since a single peice of data is
recorded at a single place(node),Why wouldn't Cassandra return the
recent value from that single
Thank you so much,

Could anyone tell me about where I can get learning resources on Cassandra?
I am beginning in cassandra to develop a social network application. Please
suggest a language/framework suitable for this purpose.
Thanks
