      The oplog is an exception to the catalog's concurrency rules: it updates its metadata in place, and acquisitions bypass two-phase locking and two-phase commit protocols. The in-place updates are racy: a read can interleave a concurrent DDL operation like oplog resizing, and read torn oplog metadata.
