# 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.

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.
