 - `coordinates`: returns recent (though not exactly up to date) binary log coordinates of the inspected server
 - `chunk-size=<newsize>`: modify the `chunk-size`; applies on next running copy-iteration
+- `dml-batch-size=<newsize>`: modify the `dml-batch-size`; applies on next applying of binary log events
 - `max-lag-millis=<max-lag>`: modify the maximum replication lag threshold (milliseconds, minimum value is `100`, i.e. `0.1` second)
 - `max-load=<max-load-thresholds>`: modify the `max-load` config; applies on next running copy-iteration
