Stop me if I misunderstood the case at hand, but while waiting some more for having a sizeable batch to send makes a lot of sense to me, waiting on the receiver side when there's some work to do will only forbids a slow slave to keep up with the load, increasing lag artificially. I'm used to asynchronous replication where you're never allowed to rest if some batch is ready for you to process. Regards, -- dim
