Where did you get this impression from? This is mostly incorrect. If you configure Kea to use a database to store leases, Kea will never cache anything in memory and will always do a DB lookup before assigning anything. The only way I can think of making Kea to keep the leases "stored in memory" would be using memfile as lease backend, but then Kea would never look up leases in a DB.

Kea doesn't work the way you think it is. Kea always looks up the lease database and never keeps any memory cache of it.
