Review Comment:
Normally if the fuc is not used outside class, we would set as private.
Also more importantly, it is a bit odd to allow user to set `ttl` but not
actually update ttl in `update`. If user provide a new `ttl` value and the
node already exit, this function will return `RetCode.OK `without actually
change anything.
