# Which Problems Are Solved
There are cases where not all statements of multiExec are succeed. This
leads to inconsistent states. One example is [LDAP
IDPs](https://github.com/zitadel/zitadel/issues/7959).
If statements get executed only partially this can lead to inconsistent
states or even break projections for objects which might not were
correctly created in a sub table.
This behaviour is possible because we use
[`SAVEPOINTS`](https://www.postgresql.org/docs/current/sql-savepoint.html)
during each statement of a multiExec.
# How the Problems Are Solved
SAVEPOINTS are only created at the beginning of an exec function not
during every execution like before. Additionally `RELEASE` or `ROLLBACK`
of `SAVEPOINTS` are only used when needed.

# Which Problems Are Solved
We identified the need of caching.
Currently we have a number of places where we use different ways of
caching, like go maps or LRU.
We might also want shared chaches in the future, like Redis-based or in
special SQL tables.
# How the Problems Are Solved
Define a generic Cache interface which allows different implementations.
- A noop implementation is provided and enabled as.
- An implementation using go maps is provided
- disabled in defaults.yaml
- enabled in integration tests
- Authz middleware instance objects are cached using the interface.
# Additional Changes
- Enabled integration test command raceflag
- Fix a race condition in the limits integration test client
- Fix a number of flaky integration tests. (Because zitadel is super
fast now!) 🎸🚀

# 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

# 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
id_tokens issued for auth requests created through the login UI
currently do not provide a sid claim.
This is due to the fact that (SSO) sessions for the login UI do not have
one and are only computed by the userAgent(ID), the user(ID) and the
authentication checks of the latter.
This prevents client to track sessions and terminate specific session on
the end_session_endpoint.
# How the Problems Are Solved
- An `id` column is added to the `auth.user_sessions` table.
- The `id` (prefixed with `V1_`) is set whenever a session is added or
updated to active (from terminated)
- The id is passed to the `oidc session` (as v2 sessionIDs), to expose
it as `sid` claim
# Additional Changes
- refactored `getUpdateCols` to handle different column value types and
add arguments for query

# Which Problems Are Solved
Implement a new API service that allows management of OIDC signing web
keys.
This allows users to manage rotation of the instance level keys. which
are currently managed based on expiry.
The API accepts the generation of the following key types and
parameters:
- RSA keys with 2048, 3072 or 4096 bit in size and:
- Signing with SHA-256 (RS256)
- Signing with SHA-384 (RS384)
- Signing with SHA-512 (RS512)
- ECDSA keys with
- P256 curve
- P384 curve
- P512 curve
- ED25519 keys
# How the Problems Are Solved
Keys are serialized for storage using the JSON web key format from the
`jose` library. This is the format that will be used by OIDC for
signing, verification and publication.
Each instance can have a number of key pairs. All existing public keys
are meant to be used for token verification and publication the keys
endpoint. Keys can be activated and the active private key is meant to
sign new tokens. There is always exactly 1 active signing key:
1. When the first key for an instance is generated, it is automatically
activated.
2. Activation of the next key automatically deactivates the previously
active key.
3. Keys cannot be manually deactivated from the API
4. Active keys cannot be deleted
# Additional Changes
- Query methods that later will be used by the OIDC package are already
implemented. Preparation for #8031
- Fix indentation in french translation for instance event
- Move user_schema translations to consistent positions in all
translation files
# Additional Context
- Closes#8030
- Part of #7809

# Which Problems Are Solved
To improve performance a new table and method is implemented on
eventstore. The goal of this table is to index searchable fields on
command side to use it on command and query side.
The table allows to store one primitive value (numeric, text) per row.
The eventstore framework is extended by the `Search`-method which allows
to search for objects.
The `Command`-interface is extended by the `SearchOperations()`-method
which does manipulate the the `search`-table.
# How the Problems Are Solved
This PR adds the capability of improving performance for command and
query side by using the `Search`-method of the eventstore instead of
using one of the `Filter`-methods.
# Open Tasks
- [x] Add feature flag
- [x] Unit tests
- [ ] ~~Benchmarks if needed~~
- [x] Ensure no behavior change
- [x] Add setup step to fill table with current data
- [x] Add projection which ensures data added between setup and start of
the new version are also added to the table
# Additional Changes
The `Search`-method is currently used by `ProjectGrant`-command side.

# Which Problems Are Solved
Adds the possibility to mirror an existing database to a new one.
For that a new command was added `zitadel mirror`. Including it's
subcommands for a more fine grained mirror of the data.
Sub commands:
* `zitadel mirror eventstore`: copies only events and their unique
constraints
* `zitadel mirror system`: mirrors the data of the `system`-schema
* `zitadel mirror projections`: runs all projections
* `zitadel mirror auth`: copies auth requests
* `zitadel mirror verify`: counts the amount of rows in the source and
destination database and prints the diff.
The command requires one of the following flags:
* `--system`: copies all instances of the system
* `--instance <instance-id>`, `--instance <comma separated list of
instance ids>`: copies only the defined instances
The command is save to execute multiple times by adding the
`--replace`-flag. This replaces currently existing data except of the
`events`-table
# Additional Changes
A `--for-mirror`-flag was added to `zitadel setup` to prepare the new
database. The flag skips the creation of the first instances and initial
run of projections.
It is now possible to skip the creation of the first instance during
setup by setting `FirstInstance.Skip` to true in the steps
configuration.
# Additional info
It is currently not possible to merge multiple databases. See
https://github.com/zitadel/zitadel/issues/7964 for more details.
It is currently not possible to use files. See

# Which Problems Are Solved
Queriying events by an aggregate id can produce high loads on the
database if the aggregate id contains many events (count > 1000000).
# How the Problems Are Solved
Instead of using the postion and in_tx_order columns we use the sequence
column which guarantees correct ordering in a single aggregate and uses
more optimised indexes.

# Which Problems Are Solved
During the implementation of #7486 it was noticed, that projections in
the `auth` database schema could be blocked.
Investigations suggested, that this is due to the use of
[GORM](https://gorm.io/index.html) and it's inability to use an existing
(sql) transaction.
With the improved / simplified handling (see below) there should also be
a minimal improvement in performance, resp. reduced database update
statements.
# How the Problems Are Solved
The handlers in `auth` are exchanged to proper (sql) statements and gorm
usage is removed for any writing part.
To further improve / simplify the handling of the users, a new
`auth.users3` table is created, where only attributes are handled, which
are not yet available from the `projections.users`,
`projections.login_name` and `projections.user_auth_methods` do not
provide. This reduces the events handled in that specific handler by a
lot.

feat(db): wrap BeginTx in spans to get acquire metrics
This changes adds a span around most db.BeginTx calls so we can get tracings about the connection pool acquire process.

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.
