# 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
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

# 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
https://github.com/zitadel/zitadel/issues/7966 for more information.

# 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.

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.

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.
