How can I get last 50 documents in mongoDB?
I have a collection which is made by
db.createCollection("collection",{capped:true, size:300000});
from this "collection"
I would like to have last 50 documents instead of get first 50 documents.
I know that I can get first 50 documents by using
db.collection.find().limit(50);
But how can I get last 50 documents?
Is this can be done simply with MongoDB API or should I implement this with programming?
this should do the thing:
db.collection.find().sort({$natural: -1}).limit(50);
