Hello,
I have recently started using Cassandra. I have designed a super column as

Can the value of a column under a super column be a super column?
For examples:
sc={
name:"name",

Hi,
I don't know whether I have missed anything here, but can we get columns for
multiple Super Column Names at a time, like what we can do for Keys (by key
range or list of keys) or columns (by column range or column list)?
