>
> An UPSERT SELECT that is running on the server-side should use a medium
> priority (lower than index priority but higher than normal priority) to
> prevent deadlocks. If we use the index priority, then there's a danger of
> deadlocks occurring if the table being upserted into also as indexes (as the
> index updates would be processed at the index priority).
