# Which Problems Are Solved
The event execution system currently uses a projection handler that
subscribes to and processes all events for all instances. This creates a
high static cost because the system over-fetches event data, handling
many events that are not needed by most instances. This inefficiency is
also reflected in high "rows returned" metrics in the database.
# How the Problems Are Solved
Eliminate the use of a project handler. Instead, events for which
"execution targets" are defined, are directly pushed to the queue by the
eventstore. A Router is populated in the Instance object in the authz
middleware.
- By joining the execution targets to the instance, no additional
queries are needed anymore.
- As part of the instance object, execution targets are now cached as
well.
- Events are queued within the same transaction, giving transactional
guarantees on delivery.
- Uses the "insert many fast` variant of River. Multiple jobs are queued
in a single round-trip to the database.
- Fix compatibility with PostgreSQL 15
# Additional Changes
- The signing key was stored as plain-text in the river job payload in
the DB. This violated our [Secrets
Storage](https://zitadel.com/docs/concepts/architecture/secrets#secrets-storage)
principle. This change removed the field and only uses the encrypted
version of the signing key.
- Fixed the target ordering from descending to ascending.
- Some minor linter warnings on the use of `io.WriteString()`.

(cherry picked from commit a9ebc06c77)
# Which Problems Are Solved
The action v2 messages were didn't contain anything providing security
for the sent content.
# How the Problems Are Solved
Each Target now has a SigningKey, which can also be newly generated
through the API and returned at creation and through the Get-Endpoints.
There is now a HTTP header "Zitadel-Signature", which is generated with
the SigningKey and Payload, and also contains a timestamp to check with
a tolerance if the message took to long to sent.
# Additional Changes
The functionality to create and check the signature is provided in the
pkg/actions package, and can be reused in the SDK.
# Additional Context
Closes#7924

# Which Problems Are Solved
The current v3alpha actions APIs don't exactly adhere to the [new
resources API
design](https://zitadel.com/docs/apis/v3#standard-resources).
# How the Problems Are Solved
- **Improved ID access**: The aggregate ID is added to the resource
details object, so accessing resource IDs and constructing proto
messages for resources is easier
- **Explicit Instances**: Optionally, the instance can be explicitly
given in each request
- **Pagination**: A default search limit and a max search limit are
added to the defaults.yaml. They apply to the new v3 APIs (currently
only actions). The search query defaults are changed to ascending by
creation date, because this makes the pagination results the most
deterministic. The creation date is also added to the object details.
The bug with updated creation dates is fixed for executions and targets.
- **Removed Sequences**: Removed Sequence from object details and
ProcessedSequence from search details
# Additional Changes
Object details IDs are checked in unit test only if an empty ID is
expected. Centralizing the details check also makes this internal object
more flexible for future evolutions.
# Additional Context
- Closes#8169
- Depends on https://github.com/zitadel/zitadel/pull/8225
