Creating a CQL3 storage layout with row key, column key and column value

[Sebastian Schmidt]

Hi,

I want to create a storage layout with CQL3 like this:
row_key should be my row key
column_key should by my column key
column_value should be the value saved for the column key

How can I achieve this?

I figured that doing this:

CREATE TABLE table_name (row_key BLOB, column_key BLOB, column_value 
BLOB, PRIMARY KEY (row_key, column_key));

would make column value unique for each row key.

But I want to store multiple key/value pairs per row. How can I do that 
with CQL3?

Kind regards,
Sebastian
