This requirement is hard to balance with strong consistency. Typically, to ensure inter-replica consistency, all replicas should receive all updates. Unfortunately, in this case, a single slow replica may degrade the performance of the whole system. This paper proposes a novel reliable broadcast primitive that uses semantic knowledge to weaken reliable delivery guarantees while, at the same time, ensuring strong consistency at the semantic level. By allowing some obsolete messages to be dropped, the protocol that implements this primitive is able to sustain a higher throughput than a fully reliable broadcast protocol. The usefulness of the primitive and the performance of the protocol are illustrated through a concrete example.&lt;/p&gt;
