@ -24,7 +24,7 @@ Both interfaces may serve at the same time. Both respond to simple text command,
- `critical-load=<load>`: change critical load setting (exceeding given thresholds causes panic and abort)
- `nice-ratio=<ratio>`: change _nice_ ratio: 0 for aggressive (not nice, not sleeping), positive integer `n`: for any `1ms` spent copying rows, spend `n*1ms` units of time sleeping. Examples: assume a single rows chunk copy takes `100ms` to complete. `nice-ratio=0.5` will cause `gh-ost` to sleep for `50ms` immediately following. `nice-ratio=1` will cause `gh-ost` to sleep for `100ms`, effectively doubling runtime; value of `2` will effectively triple the runtime; etc.
- `throttle-query`: change throttle query
- `throttle-control-replicas`: change list of throttle-control replicas, these are replicas `gh-ost` will check
- `throttle-control-replicas='replica1,replica2'`: change list of throttle-control replicas, these are replicas `gh-ost` will check. This takes a comma separated list of replica's to check and replaces the previous list.
- `throttle`: force migration suspend
- `no-throttle`: cancel forced suspension (though other throttling reasons may still apply)
- `unpostpone`: at a time where `gh-ost` is postponing the [cut-over](cut-over.md) phase, instruct `gh-ost` to stop postponing and proceed immediately to cut-over.
