AlwaysOn TDE和停机时间(AlwaysOn with TDE and Downtime)

 我对使用AlwaysOn可用性组的TDE加密相当新。 关于在实时数据库实例上应用TDE证书，我有几个问题：  
 
  您在SQL Server数据库上启用加密时遇到了什么样的停机时间？  
  在应用加密时失败到次要是一种有效的策略还是在现场应用是安全的？  
 
 任何帮助表示赞赏。 谢谢。 

I'm fairly new to using TDE encryption with AlwaysOn Availability Groups. I have a few questions regarding application of the TDE certificate on a live database instance: 
 
 What kind of downtime have you experienced for enabling encryption on a SQL server database? 
 Would failing over to the secondary when applying the encryption be a valid tactic or is it safe to be applied while live? 
 
Any help is appreciated. Thank you.

 从v0.9开始， save_png方法支持trim和trim_radius选项，因此您可以渲染一些看起来真实的卡片但仍然保持卡片边缘周围的出血区域。  
 此外，默认情况下Squib卡的背景颜色为空。 也许只是删除background color:要求卡背面？  
 （完全披露：我是Squib的开发者） 

As of v0.9, the save_png method supports a trim and trim_radius option so you can render some real-life looking cards but still maintain a bleed region around the edges of your cards.  
Also, the background color of a Squib card by default is empty. Maybe just remove the background color: call for the card backs?
