I’m working with a database MongoDB and due to the high consumption of resources (work with a dataset of almost 100GB), I need to shrink the field names of documents (something like “ALTER TABLE”).
Is there an easy / automatic to do this?

I think so! Check out
$rename: http://www.mongodb.org/display/DOCS/Updating#Updating-%24renameRun an
update()on your data set with a query with a bunch of$renames and I think that will get you what you want.
