# 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()`. # Additional Context - Introduced in https://github.com/zitadel/zitadel/pull/9249 - Closes https://github.com/zitadel/zitadel/issues/10553 - Closes https://github.com/zitadel/zitadel/issues/9832 - Closes https://github.com/zitadel/zitadel/issues/10372 - Closes https://github.com/zitadel/zitadel/issues/10492 --------- Co-authored-by: Stefan Benz <46600784+stebenz@users.noreply.github.com>
