Enum Refs 

pub enum Refs {
    Keep,
    Drop,
    Acked,
}

What a delete does about the consumer groups still pointing at the entry.

XDEL takes an entry out from under whoever was handed it and leaves the pending list holding an ID that can never be read, which is a state XCLAIM then has to clean up. The 8.2 commands let a caller say what it wants instead, and the three answers are the three words here.

Variants

Keep

KEEPREF: take the entry and leave every pending list alone, which is what XDEL has always done and is still the default.

Drop

DELREF: take the entry and take it out of every pending list with it.

Acked

ACKED: only take the entry when no group could still be handed it.
