Oracle NoSQL and indexing

Question

Hi all,
I read that there is an index on key value on each node.
Does that mean that as soon as we have the good key, there is a full scan on all the values for that key on that node?
So to have better performance should we have many keys and fewer values?
Thanks

When I look for the key username, I expect to have a name as value.So, for me it is the key which help me to know what type of value is stored there.
Am I wrong?>
I think you are right, but you are using the wrong terminology. Here is the correct terminology: In general a key is a major path and a minor path, where each path is a list of strings. In your case, I believe you're only using the major path. Your major path has two components (two strings). The first component (the constant 'username') tells you what to expect in the second component ('John' or 'Jeff').
You can think of the second component of your key path as a variable rather than a constant component. But please don't call it a value, since the term value is reserved for something else -- it is the data associated with the key in the key-value pair. After all, this is a key-value store, so key and value are pretty important terms.
