Given What is difference between Lightsail and EC2? and my own testing, I am convinced that LightSail Instances are burstable performance instances.
Are LightSail database instances subject to this kind of burstable performance too? I'm interested in both I/O burst and CPU burst.
If so, is there a way to view the remaining CPU or IO burst credits? Unlike EC2, the web console for LightSail doesn't seem to offer these numbers.
