amazon rds – How does AWS DMS on-going replication works internally?

From the documentation it’s mentioned that “DMS collects changes to the database logs using the database engine’s native API” and replicates to target. But, I didn’t see anywhere that, at what rate it replicates from source to target in terms of number of records and is there any way we can control this settings or can I know each time how many rows it replicates?
