we have a scene that we need traverse the whole collection ,and also record where we traverse to so that we can continue to do it if process failed,
I try update and delete some documents and db.collecton.find() return the same order but I can't find some issue to explain whether it is clustered index about wiredTiger. In MMAP I know it could change the location of data and find() return unordered.
So I want to confirm in wiredtiger whether some operations can lead to db.collection.find() return unordered not include chunk moving in th shard or wiredtiger use clustered index ?
