Keys This class defines: - A Key's bytes (name) & hash - Known Disk & memory replicas. - A cache of somewhat expensive to compute stuff related to the current Cloud, plus a byte of the desired replication factor. Keys are expected to be a high-count item, hence the care about size. Keys are *interned* in the local K/V store, a non-blocking hash set and are kept pointer equivalent (via the interning) for cheap compares. The interning only happens after a successful insert in the local H2O.STORE via H2O.put_if_later.
