suppose, I have an existing capped collection with the following syntax.

db.createCollection("mycappedCollection",{capped: true, size: 2, max:2})

Now, what i want is to modify the above collection and add the autoIndexId option.
like:

db.createCollection("mycappedCollection",{capped: true, autoIndexId: true, size: 2, max:2})

How can I modify the existing mycappedCollection?

To change collection options, you need to create a new collection, copy all data from old one, then drop old one. This will spend a long time to complete when you have a large collection.

I have a DB with several (quite big) collections, on Mongo 3.2.5 and WiredTiger with snappy compression on. I would like to change the compression setting on one small collection I have to test it uncompressed. Is there a possibility to do that on a secondary without having to resync the whole DB?
