Abstract
Annulment of events written into an ordered event stream (OES) storage system is disclosed. Events can be written to one or more segments of an OES. An event can be invalid and overwriting the event can be desirable. A stream-cut event can be employed to facilitate annulment of the event via altering a portion of a segment of an OES. The stream-cut event can be durable. Annulment can avoid rewriting an entire stream and/or complicating a stream by adding mitigating events without overwriting invalid events. In an aspect, annulment can comprise moving a write cursor according to a stream-cut event. The annulment can be lossy or lossless. In an embodiment, annulment can be performed in single tier OES storage system. In another embodiment, multi-tier OES storage systems can facilitate annulment.
