Abstract: A graph tracks the lineage of customer data, including when it was originally extracted from a customer computing system, and any transformation results indicating transformations that were performed on the customer data. The graph is traversed to identify nodes in the graph that have expired based upon data removal policies. The customer data represented by the expired nodes in the graph is deleted and the graph is modified to delete the expired nodes. The modified graph is then stored in persistent memory until data removal is next triggered.

Abstract: A configuration system is described. In an implementation, a method includes determining through execution of a configuration system whether an application qualifies as a member of one or more of a plurality of groups. Each of the groups defines one or more criteria for membership and has at least one corresponding block having configuration data. The determining is performed based on whether the application satisfies the one or more criteria. For each of the groups, of which, the application qualifies as a member, the configuration data of the at least one corresponding block is loaded.

Abstract: Efficient processing of time-bound messages is described herein. In an implementation, messages are classified either time-bounded messages or non-time-bounded messages. The time-bounded messages are then processed separately from the non-time-bound messages. Examples of time-bounded messages can include spam e-mails or other types or classes of e-mails subject to a retention policy, such that the are retained only for some set period of time. Metadata relating to the time-bound messages are compiled and stored separately from the messages, thereby enabling optimization of the metadata storage and processing apart from the messages. The time-bounded messages are accumulated before they are processed in bulk, thereby reducing the number if I/O operations consumed by the time-bound messages, and reducing the amount and cost of resources supporting the process of the time-bounded messages.
