>                 Key: MESOS-10216
>                 URL: https://issues.apache.org/jira/browse/MESOS-10216
>             Project: Mesos
>          Issue Type: Bug
>          Components: replicated log
>    Affects Versions: 1.11.0
>            Reporter: Ilya
>            Priority: Major
>
> 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.
