> When there are many events in the cloud.event table, the UI throws an SQL exception and the management server spikes at 100% CPU for minutes. That causes other API calls to fail with 430 errors.
> Studying the error below, it seems an index on the 'archived' field is missing (since it is used in the WHERE clause).
> We have 1.4M events in the table:
> select count(*) from event;
> 1497838
> Solution:
> Please add the index to the archived field and consider doing the same for the state field.
> Work around:
> Delete events manually
> delete from event where state = "Completed";
> Since state also does not have an index, this takes some time.
