My intention is to cache the result of searchPlaceIndexForPosition . For that, I used Storage as DataSourceConfiguration. That's because the developer guide states that :

Storage specifies that the result can be cached or stored in a database.

Yet, some areas are still obscure to me:

• Does AWS store/cache the data or it's left to me to do so?
• If AWS stores it:
  • how long does AWS retain the data?
  • What is the cache expiration?

I've had hard time finding docs that answer those questions. Perhaps I'm asking the wrong ones. Please point me to the right repository/channel if this question is out of scope here.
