@ -19,6 +19,7 @@ Both interfaces may serve at the same time. Both respond to simple text command,
- `sup`: returns a brief status summary of migration progress
- `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
- The `max-load` format must be: `some_status=<numeric-threshold>[,some_status=<numeric-threshold>...]`'
