Subject: about partitioner in cluster

Hi,

I am new to Cassandra.
I have some questions about the cluster partitioner.

It looks like once I set the partitioner, there is no way to change it
later.

However, in our application, some keyspaces need to be sorted based on key,
some don't.
Is there a flexible way to define a cluster to contain different keyspaces
with different order preference?

thanks
zhenyu
