# Which Problems Are Solved
The connection pool of go uses a high amount of database connections.
# How the Problems Are Solved
The standard lib connection pool was replaced by `pgxpool.Pool`
# Additional Changes
The `db.BeginTx`-spans are removed because they cause to much noise in
the traces.
# Additional Context

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.
