A content platform (or“cluster”) that comprises a redundant array of independent nodes is logically partitioned. Using a web-based interface, an administrator defines one or more“tenants”within the cluster, wherein a tenant has a set of attributes: namespaces, administrative accounts, data access accounts, and a permission mask. A namespace is a logical partition of the cluster that serves as a collection of objects typically associated with at least one defined application. Each namespace has a private file system with respect to other namespaces. This approach enables a user to segregate cluster data into logical partitions. Using the administrative interface, a namespace associated with a given tenant is selectively configured without affecting a configuration of at least one other namespace in the set of namespaces. One configuration option is a“disposition service”that, once enabled for a namespace, automatically deletes objects that were once under retention and whose retention time has expired. Preferably, the disposition service deletes objects that do not have a“retention hold”associated therewith. The service enables the content platform to automatically reclaim cluster capacity while minimizing external involvement and archive load. |
