DynamoDB - Multiple range keys Is it possible to have multiple fields as range key?

Say I have a table where each row is uniquely identified by &lt;A,B,C&gt;

 -------------------------------
 A   |   B   |  C  |  D   |  E  |
 -------------------------------


where A is the primary hash key

and I want B and C to be the primary range keys.


  How can I have more than 2 fields as a primary key in DynamoDB?
Put a copy of B and C in the range field (as an extra column) and make that your range key like "B_C" and you can still also have separate columns for B and C if you need.
