# Which Problems Are Solved Add a debug API which allows pushing a set of events to be reduced in a dedicated projection. The events can carry a sleep duration which simulates a slow query during projection handling. # How the Problems Are Solved - `CreateDebugEvents` allows pushing multiple events which simulate the lifecycle of a resource. Each event has a `projectionSleep` field, which issues a `pg_sleep()` statement query in the projection handler : - Add - Change - Remove - `ListDebugEventsStates` list the current state of the projection, optionally with a Trigger - `GetDebugEventsStateByID` get the current state of the aggregate ID in the projection, optionally with a Trigger # Additional Changes - none # Additional Context - Allows reproduction of https://github.com/zitadel/zitadel/issues/8517
