mongodb delete by timestamp
The ObjectId of the document is basically contains timestamp. So you can easily construct ObjectId from timestamp and use $lt operator just like ..., collectionName.find(}, _id : 1}) .limit(100) .sort(timestamp:-1}) .toArray() ... FYI: you cannot remove documents from a capped collection.
