Workers KV "Set arbitrary TTLs for values"?

I am trying to decipher the meaning of this phrase in KV features:
“Set arbitrary TTLs for values”

Does it mean you can set TTL on a KV pair? If so, how to?

This means you can write a value which “self-destructs” / deletes itself after some set amount of time. This is a new feature which actually isn’t totally rolled out yet. We’ll extend the documentation to cover it once it’s ready.
