this is similar to an asynchronously replicated database replica.
Which mean read might return stale data because of the replication lag.
It will also increase the load on the server you read the replication log from.
But the primary database could dump the transaction log to (S3/kafka) and have ReadySet instance read it from there instead of directly from Primary database.
So for a read mostly website (hackernews/reddit) this is indeed a free lunch.
