Amazon Aurora 宣佈支援快速複製:「Amazon Aurora Fast Database Cloning」。
對於 2TB 的資料大約五分鐘就完成了:
This means my 2TB snapshot restore job that used to take an hour is now ready in about 5 minutes – and most of that time is spent provisioning a new RDS instance.
主要是得力於後端 storage 的部份可以實做 copy-on-write 架構:
By taking advantage of Aurora’s underlying distributed storage engine you’re able to quickly and cheaply create a copy-on-write clone of your database.
可以快速複製就可以很快的驗證一些事情,像是可以直接測試 ALTER TABLE
需要的時間,或是事前演練...
