Abstract
Access control for an ordered event stream (OES) storage system is disclosed. Access to a portion of an OES can be controlled at a key-level in relation to a key space of the OES. An application instance can be identified to enable determining a correspondence to one or more keys. The correspondence can be embodied in stored data, for example, via an advanced access control list (AACL) that can be in the form of a list, a table, etc. Application instance access to the portion of the OES can be controlled by determining if an access rule is satisfied, e.g., determining if the key space the application instance wants to access comports with the one or more keys corresponding to the application instance identity. In an aspect, screening data corresponding to the AACL can enable preliminary access screening external to the OES storage system.
