Hi Scott,

Key is removed immediately from the in-memory hash table "keydir", when
expired. One cannot access the value of that key after expiry, meaning "the
data", although it physically exists. Data removal happens during the merge
process.

Hi there,

When expired, at what point will the key be removed from memory? Is the
expiration process automated, or trigged by a read?

Thanks!
Scott
