# Which Problems Are Solved
Optimize the query that checks for terminated sessions in the access
token verifier. The verifier is used in auth middleware, userinfo and
introspection.
# How the Problems Are Solved
The previous implementation built a query for certain events and then
appended a single `PositionAfter` clause. This caused the postgreSQL
planner to use indexes only for the instance ID, aggregate IDs,
aggregate types and event types. Followed by an expensive sequential
scan for the position. This resulting in internal over-fetching of rows
before the final filter was applied.
Furthermore, the query was searching for events which are not always
applicable. For example, there was always a session ID search and if
there was a user ID, we would also search for a browser fingerprint in
event payload (expensive). Even if those argument string would be empty.
This PR changes:
1. Nest the position query, so that a full `instance_id, aggregate_id,
aggregate_type, event_type, "position"` index can be matched.
2. Redefine the `es_wm` index to include the `position` column.
3. Only search for events for the IDs that actually have a value. Do not
search (noop) if none of session ID, user ID or fingerpint ID are set.
New query plan:
# Additional Changes
- cleanup how we load multi-statement migrations and make that a bit
more reusable.

# Which Problems Are Solved
Float64 which was used for the event.Position field is [not precise in
go and gets rounded](https://github.com/golang/go/issues/47300). This
can lead to unprecies position tracking of events and therefore
projections especially on cockcoachdb as the position used there is a
big number.
example of a unprecies position:
exact: 1725257931223002628
float64: 1725257931223002624.000000
# How the Problems Are Solved
The float64 was replaced by
[github.com/jackc/pgx-shopspring-decimal](https://github.com/jackc/pgx-shopspring-decimal).
# Additional Changes
Correct behaviour of makefile for load tests.
Rename `latestSequence`-queries to `latestPosition`
# Which Problems Are Solved
The access token verifier returned a permission denied (HTTP 403 / GRPC
7) instead of a unauthenticated (HTTP 401 / GRPC 16) error.
# How the Problems Are Solved
Return the correct error type.
# Additional Changes
None

# Which Problems Are Solved
Access token checks make sure that there have not been any termination
events (user locked, deactivated, signed out, ...) in the meantime. This
events were filtered based on the creation date of the last session
event, which might cause latency issues in the database.
# How the Problems Are Solved
- Changed the query to use `position` instead of `created_at`.
- removed `AwaitOpenTransactions`
# Additional Changes
Added the `position` field to the `ReadModel`.
# Additional Context
- relates to #8088
- part of #7639
- backport to 2.53.x

* handle all errors in defer
* do not fail auth request on error
the oauth2 Go client automagically retries on any error. If we fail the auth request on the first error, the next attempt will always fail with the Errors.AuthRequest.NoCode, because the auth request state is already set to failed.
The original error is then already lost and the oauth2 library does not return the original error.
Therefore we should not fail the auth request.
Might be worth discussing and perhaps send a bug report to Oauth2?

This implementation increases parallel write capabilities of the eventstore.
Please have a look at the technical advisories: [05](https://zitadel.com/docs/support/advisory/a10005) and [06](https://zitadel.com/docs/support/advisory/a10006).
The implementation of eventstore.push is rewritten and stored events are migrated to a new table `eventstore.events2`.
If you are using cockroach: make sure that the database user of ZITADEL has `VIEWACTIVITY` grant. This is used to query events.
This PR adds support for the OIDC end_session_endpoint for V2 tokens. Sending an id_token_hint as parameter will directly terminate the underlying (SSO) session and all its tokens. Without this param, the user will be redirected to the Login UI, where he will able to choose if to logout.
This PR adds support for OAuth2 token revocation of V2 tokens.
Unlike with V1 tokens, it's now possible to revoke a token not only from the authorized client / client which the token was issued to, but rather from all trusted clients (audience)
This PR adds support for userinfo and introspection of V2 tokens. Further V2 access tokens and session tokens can be used for authentication on the ZITADEL API (like the current access tokens).
