Where did you see that the end of FDB key space whas #xFF a certain number of times? I only know that everything after #xFF is for internal use.
Nowhere, but it's only logic. The keys are compared lexicographically, and if two keys are the same up to the end of the shorter one, the longer one is considered larger. Therefore, the largest possible key contains all #xFF bytes and is as long as a key can be, which in FoudationDB is 10,000 bytes.
