# Which Problems Are Solved
The setup filter for previous steps and kept getting slower. This is due
to the filter, which did not provide any instanceID and thus resulting
in a full table scan.
# How the Problems Are Solved
- Added an empty instanceID filter (since it's on system level)
# Additional Changes
None
# Additional Context
Noticed internally and during migrations on some regions
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.
* fix(setup): unmarshal of failed step
* fix(cleanup): cleanup all stuck states
* use lastRun for repeatable steps
* typo
