ABSTRACT:
A database or some portion thereof is partitioned into ownership groups. Each ownership group is assigned one or more database servers as owners of the ownership group. The database servers that are assigned as owners of an ownership group are treated as the owners of all data items that belong to the ownership group. That is, they are allowed to directly access the data items within the ownership group, while other database servers are not allowed to directly access those data items. Accordingly, at least a portion of the database is partitioned into a plurality of ownership groups. Each ownership group is assigned an owner set. Only processes that are executing on database servers that are members of the owner set of an ownership group are allowed to directly access data within the ownership group.
