Clustering Footnote B

Cluster in the sense of ObjectStore, i.e. an os_cluster from version 6.0 on or an os_object_cluster for 5.1 and predecessor. In the following text cluster (in the singular) refers to a database cluster in this technical sense, while clustering means the mechanism of combining or separating objects in the database, even though ObjectStore 5.1 sometimes does not use os_object_clusters but only segments.
