Amazon RDS 的升級：「Amazon RDS Now Supports Database Storage Size up to 16TB and Faster Scaling for MySQL, MariaDB, Oracle, and PostgreSQL Engines」。
空間上限從 6TB 變成 16TB，而且可以無痛升。另外 IOPS 上限從 30K 變成 40K：
Starting today, you can create Amazon RDS database instances for MySQL, MariaDB, Oracle, and PostgreSQL database engines with up to 16TB of storage. Existing database instances can also be scaled up to 16TB storage without any downtime.
The new storage limit is an increase from 6TB and is supported for Provisioned IOPS and General Purpose SSD storage types. You can also provision up to 40,000 IOPS for Provisioned IOPS storage volumes, an increase from 30,000 IOPS.
不過隔壁的 Amazon Aurora 還是大很多啊 (64TB)，而且實際上不用管劃多大，他會自己長大：
Q: What are the minimum and maximum storage limits of an Amazon Aurora database?
The minimum storage is 10GB. Based on your database usage, your Amazon Aurora storage will automatically grow, up to 64 TB, in 10GB increments with no impact to database performance. There is no need to provision storage in advance.
