Suggestion about syntax of CREATE COLUMN FAMILY

[Don Smith]

Currently, the syntax for creating column families is like this:

create column family Users
with comparator=UTF8Type
and default_validation_class=UTF8Type
and key_validation_class=UTF8Type;

It's not clear what "comparator" and "default_validation_class" refer to. Much 
clearer would be:

create column family Users
with column_name_comparator=UTF8Type
and column_value_validation_class=UTF8Type
and key_validation_class=UTF8Type;

BTW, instead of "column_name_comparator", I'd actually prefer 
"column_key_comparator" since it seems more accurate to call column names 
"column keys."
