> In cqlsh, the desc table command does not make it sufficiently clear which
> columns are part of the row key and which are clustering keys.
> A simple change to the primary key list, though, would make it easier to tell.
> Consider the following table definition:
> {code}
> create table my_table {
> first_column text,
> second_column text,
> third_column text,
> primary key (first_column, second_column, third_column)
> }
> {code}
> This table has a row key of first_column and clustering keys of
> second_column, third_column. But if the user intended for the table to have
> all three in the row key, the correct definition would be:
> {code}
> create table my_table {
> first_column text,
> second_column text,
> third_column text,
> primary key ((first_column, second_column, third_column))
> }
> {code}
> But this is a sufficiently subtle difference that the first may be mistaken
> for the second or vice-versa.
> My suggested solution is to always wrap the row key in parentheses. This is
> already supported by create table syntax, so it's just a matter of changing
> desc table to display the create table statement with the primary key always
> in parentheses, like so:
> {code}
> create table my_table {
> first_column text,
> second_column text,
> third_column text,
> primary key ((first_column), second_column, third_column)
> }
> {code}
