* fix(eventstore): prevent allocation of filtered events Directly reduce each event obtained from a sql.Rows scan, so that we do not have to allocate all events in a slice. * reinstate the mutex as RWMutex * scan data directly * add todos * fix(writemodels): add reduce of parent * test: remove comment * update comments --------- Co-authored-by: adlerhurst <silvan.reusser@gmail.com>
