Cassandra 0.8.1: request for a sub-column still deserializes all sub-columns for that super column?

[Oleg Tsvinev]

Hi All,

Cassandra documentation here:

http://www.datastax.com/docs/0.8/data_model/supercolumns

states that:

Any request for a sub-column deserializes all sub-columns for that super
column, so you should avoid data models that rely on on large numbers of
sub-columns.

Is this still true?

Thank you,
  Oleg
