>
> When building the Directory component of ClusterMetadata, the entire set of
> nodes is traversed to calculate the min, max and common serialization
> versions. Deserializing a directory from a set of bytes (e.g. when reading a
> snapshot from the system table or off the wire) is inefficient and creates a
> new temporary Directory instance each time a node is added. In large clusters
> this may have a noticeable effect on loading time.
