[Clarification] Is cache scoped to instance about apollo-cache-persist

@jamesreggio - Ah perfect, I missed the key API, so that clears up the confusion, thanks!

Hi @JasonLi914 — you're correct. The cache persistor is scoped to the cache that it's attached to. That is to say, when you call persistor.purge(), it will only delete the key in the storage provider that it is managing.

If you have multiple caches and persistors, you need to pass a unique key to each persistor so they don't both use the same default value and write over each other.

Please let me know if that answers your question.
