+# Configure Milvus on the Fly
+
+Milvus allows you to change some of its configurations on the fly.
+
+## Before you start
+
+You need to ensure that：
+
+- You have Birdwatcher installed. For details, refer to [Install Birdwatcher](birdwatcher_install_guides.md),
+- You have etcdctl installed. For details, refer to [Interacting with etcd](https://etcd.io/docs/v3.5/dev-guide/interacting_v3/), or
+- You have other etcd clients, such as the Python client, installed.
+
+
+
+- Examples in this guide change the value of `proxy.minPasswordLength` to `8`. You can replace the key with the applicable ones listed in
+- Examples in this guide assume that the root path of your Milvus is `by-dev`. All configurations are listed under the path `by-dev/config`. The Milvus root path varies with the way you install it. For the instances installed using the Helm charts, the root path defaults to `by-dev`. If you do not know the root path, refer to [Connect to etcd](birdwatcher_usage_guides.md#Connect-to-etcd).
+
+
+
+## Change configurations
+
+On Milvus, `proxy.minPasswordLength` is set to `6` by default. To change this value, you can do as follows:
+
+```shell
+$ etcdctl put by-dev/config/proxy/minPasswordLength 8
+# or
+$ birdwatcher -olc "#connect --etcd 127.0.0.1:2379 --rootPath=by-dev,set config-etcd --key by-dev/config/proxy/minPasswordLength --value 8"
+```
+
+Then you can check the configurations as follows:
+
+```shell
+$ etcdctl get by-dev/config/proxy/minPasswordLength
+```
+
+## Roll back configurations
+
+Milvus also allows you to roll back your configurations in case the changed value no longer applies.
+
+```shell
+$ etcdctl del by-dev/config/proxy/minPasswordLength
+# or
+$ birdwatcher -olc "#connect --etcd 127.0.0.1:2379 --rootPath=by-dev,remove config-etcd --key by-dev/config/proxy/minPasswordLength"
+```
+
+Then you can check the configurations as follows:
+
+```shell
+$ etcdctl get by-dev/config/proxy/minPasswordLength
+```
+
+## View configurations
+
+Instead of viewing the value of a specific configuration item, you can also list all of them.
+
+```shell
+$ etcdctl get --prefix by-dev/config
+# or
+$ birdwatcher -olc "#connect --etcd 127.0.0.1:2379 --rootPath=by-dev,show config-etcd"
+```
+
+To view the configurations of a specific node:
+
+```shell
+Offline > connect --etcd ip:port
+Milvus(by-dev) > show session # List all nodes with their server ID
+Milvus(by-dev) > visit querycoord 1 # Visit a node by server ID
+QueryCoord-1(ip:port) > configuration # List the configuration of the node
+```
+
+## Applicable configuration items
+
+Currently, you can change the following configuration items on the fly.
