Abstract: Systems, methods, and computer-readable media for event sourcing datastores are provided. Events are sent to an event sourcing datastore (ESDS) from an external service, and the events are appended to an event log. The ESDS maintains the event log in one table and the events are automatically aggregated via streaming. The ESDS is linearly scalable, and enforces uniqueness, consistency, and user-defined constraints when appending events to the event log. The aggregate state is computed asynchronously and transparently cached, which provides increased read throughput and reduced latency. Other embodiments may be described and/or claimed.
