BTW, do you know how users deal with this lag? For example, one can imagine creating multiple pub-sub pairs for different sets of tables so that the workload on the subscriber could also be shared by multiple apply workers. I can also think of splitting the workload among multiple pub-sub pairs by using row filters. -- With Regards, Amit Kapila.
