I've a MongoDB collection that works like a queue: new documents are insert and old documents (after 60days) are removed. I can see a rapid grown of the datafile size, too rapid. I can be reasonable because we remove old data after 60 days, but I was thinking, are my deletes effective without execute the defragmentation? (in few words, what's a good way to manage disk space in MongoDB)
What is a correct defragment / clean collection politics? It's a production database and version is 2.6.9
thanks.
