> LevelDB keys used by {{LevelDBStorage}} are {{uint64_t}} log positions encoded as strings and padded with zeroes up to a certain fixed size. The {{encode()}} function is incorrect because it uses the {{%d}} formatter that expects an {{int}}. It also limits the key size to 10 digits which is OK for {{UINT32_MAX}} but isn't enough for {{UINT64_MAX}}.
> Because of this the available key range is reduced, and key overflow can result in replica's {{METADATA}} record (position 0) being overwritten, which in turn may cause data loss.
