# Which Problems Are Solved
Do not push secret succeeded and failed events for API and OIDC clients
on the introspection endpoint.
On instances where introspection was fequently called, the pushed events
created issues on duplicate primary keys, due to collisions on the
`sequence` column in the eventstore. As the event pusher retries on this
collision and we pushed above mentioned events async, it would create a
backpressure of concurrent pushers and effectively cripple an instance.
We considered that pushing these events have little value with regards
to the audit trail, as we do not push similar events when client
assertion is used. Also, before #7657 the events were defined, but not
pushed.
# How the Problems Are Solved
- Removed API secret check succeeded and faild event definitions
- Removed OIDC secret check succeeded and faild event definitions
- Push only Hash Updated event when needed
# Additional Changes
- None
# Additional Context
- Fixes https://github.com/zitadel/zitadel/issues/8479
- Closes https://github.com/zitadel/zitadel/issues/8430
- Intoduced in https://github.com/zitadel/zitadel/pull/7657
Even though this is a feature it's released as fix so that we can back port to earlier revisions.
As reported by multiple users startup of ZITADEL after leaded to downtime and worst case rollbacks to the previously deployed version.
The problem starts rising when there are too many events to process after the start of ZITADEL. The root cause are changes on projections (database tables) which must be recomputed. This PR solves this problem by adding a new step to the setup phase which prefills the projections. The step can be enabled by adding the `--init-projections`-flag to `setup`, `start-from-init` and `start-from-setup`. Setting this flag results in potentially longer duration of the setup phase but reduces the risk of the problems mentioned in the paragraph above.
