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.
