The primary key of the item where the operation stopped, inclusive of the previous result set. Use this value to start a new operation, excluding this value in the new request. If LastEvaluatedKey is null, then the "last page" of results has been processed and there is no more data to be retrieved. If LastEvaluatedKey is anything other than null, this does not necessarily mean that there is more data in the result set. The only way to know when you have reached the end of the result set is when LastEvaluatedKey is null.
