Question

I have a simple database with couch db. I have users have that fields:

String userName
String password
String mail
boolean admin

I keep my users at db. However I am so new to Couch DB and NoSql. How can I implement map reduce on it with an example (or does it do it internally and I don’t need to do anything?)

I use Spring 3 and Ekorp for my application.

Answer 1

in couch,
add a field in your documents called

_type

or

type_

The map function could be

function(doc) {
 if(doc.type_=="user") { 
   emit(doc.name,doc._id);
 }
}
