To retrieve the value for the key named "redis/config/connections" in the
KV store:
```shell-session
```shell-session hideClipboard
$ consul kv get redis/config/connections

This will return the original, raw value stored in Consul. To view detailed
information about the key, specify the "-detailed" flag. This will output all
known metadata about the key including ModifyIndex and any user-supplied
flags:

To just list the keys which start with the specified prefix, use the `-keys`
option instead. This is more performant and results in a smaller payload:
