I'm afraid that is not true. The shard allocation for two different shard types
are independent of each other. The order of when the shards are requested
matter, at least when using the default shard allocation strategy.
On the other hand, it might matter for you where the persistent view is
running. I can't see an advantage of running it in same jvm as the persistent
actor.
