Abstract
Retention of events of an ordered event stream according to at least one triggered retention policy is disclosed. Expiration of events stored in a segment of an ordered event stream (OES) can be desirable. New events can be added to a head of an OES segment, and pruning events from a tail of the OES segment can be desirable. Processing applications can predicate event retention, e.g., restricting expiration of an event, on at least one triggered retention policy. In some embodiments, an additional fixed retention policy can be combined with the triggered retention. The disclosed retention can be performed at the event-level or at less granular levels, e.g., segment-level, OES-level, etc., e.g., via batching of events.
