 1. Key expiration is performed as a local operation on each cluster node. The reason for this is that expiration depends on a local clock as well as on active expiry logic; thus, volatile keys may violate consistency.

    For example, avoid using non-deterministic commands such as `RANDOMKEY`, `SRANDMEMBER`, and `TIME`, as these will produce different values when executed on follower nodes.
