If you’re working with an Aurora database in serverless mode, you might want to set the minimum capacity for your cluster. This setting ensures that your database doesn’t scale down too much during low usage periods, which can help maintain performance and stability.
To set this, you can specify the minimum capacity, but keep in mind it must be lower than or equal to the maximum capacity you choose. For Aurora MySQL, valid capacity numbers range from 1 to 256, including options like 1, 2, 4, 8, 16, 32, 64, 128, and 256. For Aurora PostgreSQL, the options are slightly different, including 2, 4, 8, 16, 32, 64, 192, and 384.
By default, if you don’t specify a minimum capacity, it will be set to 1. Choosing a higher minimum capacity can help your database handle more consistent workloads without scaling down too much during periods of low activity. Just remember to choose a value that makes sense for your app’s needs and stays within the valid options.
