Description
This page doesn't make clear that the oplog size we set is actually the document size and not the storage size (like I believe it was in MMAP?). So we should expect that the actual storage size on disk would be a fraction of this oplog size. This might be important information for customers (like mine) who will need an oplog of about 60GB of documents (uncompressed) but which actually takes only 15GB on disk.
