In a multi node HA deployment for production does key rotate need a keystone process reboot or should we just run the fernet rotate on one node and distribute it without restarting any process<br>
I presume keystone can handle the rotation without a restart?<br>
<br>
I also assume this key rotation can happen without a maintenance window<br>
<br>
What do folks typically do in production and how often do you rotate keys<br>
