EventTableIt is up to the index to decide whether to add first and then remove, or whether to remove and then add.
It is important to note that a given event can be in both the removed and the added events. This means that unique indexes probably need to remove first and then add. Most other non-unique indexes will add first and then remove since the an event can be both in the add and the remove stream.
