That's a good point. We mention latency as "replication lag" and we have devoted a paragraph to the drift that comes as the result of this latency. In our case,

That's a good point. We mention latency as "replication lag" and we have devoted a paragraph to the drift that comes as the result of this latency. In our case, we measured the latency to be <1s, and it was totally acceptable. As for the performance, triggers can become a problem with enough write traffic. In a different use case, Bucardo would be eliminated from a potential solution due to this.
