Abstract
Event prioritization for an ordered event stream (OES) is disclosed. Unlike conventional prioritization techniques, the disclosed subject matter can be performed by an OES data storage system to provide direct, rather than indirect, control of prioritization. In an embodiment, a prioritized hashed key (PHK) can be determined from an event characteristic and an indicated event priority value based on a selectable priority-sensitive hashing function. As such, events with a same key characteristic but different indicated priorities can have different PHKs, events with different key characteristics but the same indicated priority can have different PHKs, and events with the same key characteristic and the same priority can have a same PHK. An event priority can be inherently comprised in the PHK without needing to explicitly store the priority value with a written event in the OES. Moreover, the disclosed prioritization for the OES can be compatible with OES scaling techniques.
