Does this just mean the exhaustive list of the column names not all
the values?
No, this means the entire supercolumn, names and values. When the client
tries to access any subcolumn in the supercolumn it has to read the
entire supercolumn.
So if I have a super column that has a map of keys that only contain
two columns max each this shouldn't really be a performance concern
correct? This becomes an issue when you have lots of subcolumns if I'm
reading this correctly? I'm looking at using the super column as a
good way to cluster data, say I was storing home addresses I might use
the zipcode as the super column if I cared mostly about accessing data
by logical area for instance. Thanks for the help.
That is one way to logically group the values, but I think that a
simpler solution may be to store the home address as a single row in a
column family, then use a dynamic column family to store references to
those addresses per zip code.
