It is not just ARM instances. Parallel Query, Multi-Master, and Performance Insights, are all locked to specific classes of x86 instances.
It's like Amazon has narrowly tested specific features on specific hardware sizes.
- ashtonkem 6y agoOn one hand, it's incredibly annoying. On the other hand part of why you'd choose RDS over deploying MariaDB yourself to an EC2 instance is to shift some of the responsibility of testing & configuration over to AWS. If AWS is disabling features on instances that don't work, this is actually a benefit that they're providing to their users, as you can better trust that any feature enabled on a given product & instance type will "just work".

When you're making a promise to a large number of customers that you're going to support something for the long term it's understandable that you're going to be conservative and probably run some sort of closed beta for long enough to get solid operational experience.
- sandinmyjoints 6y agoIs there somewhere that lists which features are enabled on which instances? We were thinking of switching to Graviton2 RDS instances but not being able to use Performance Insights would be an important factor in making or not making that switch.
