缩容 Pump 需要先将单个 Pump 节点从集群中下线，然后运行 `helm upgrade` 命令将对应的 Pump Pod 删除，并对每个节点重复上述步骤。


1. 下线 Pump 节点：

假设现在有 3 个 Pump 节点，我们需要下线第 3 个 Pump 节点，将 `<ordinal-id>` 替换成 `2`，操作方式是：

{{< copyable "shell-regular" >}}

```shell
kubectl run offline-pump-<ordinal-id> --image=pingcap/tidb-binlog:<version> --namespace=<namespace> --restart=OnFailure -- /binlogctl -pd-urls=http://<release-name>-pd:2379 -cmd offline-pump -node-id <release-name>-pump-<ordinal-id>:8250
```

`<version>` 为当前 TiDB 的版本。

然后查看 Pump 的日志输出，确认输出 `pump offline, please delete my pod` 后即可确认该节点已经成功下线。
