Execute Collection Migrations on multiple Cores

[Christian Schneider]

Hi,

is there any chance to execute the schema changes on multiple cores?

Usually our updates are not that easy that they can be done by the "update" language MongoDB provides.

Therefore we write them mostly like this:

db.col.findAll().forEach(function(doc) {

   // do all the update magic here...

   save(doc);

});

But the problem is that the cursor stuff only works on a single core.

Any idea how to migrate faster? :)

Best Regards,

Christian.
