T2 Unlimited for RDS instances

Question

Hi,  
I recently hit a CPUCreditBalance of 0 on my t2.micro RDS instance which was not so great.  
For regular EC2 t2 instances you can change the "credit type" to T2 Unlimited which disables throttling when the balance is depleted. However, I can't seem to find this option for RDS instances.  
Is T2 Unlimited not supported for RDS instances?

Accepted Answer

RDS has not announced support for Unlimited versions of the db.t2 instance family.  Hopefully that is something that is coming soon, but I haven't seen anything to confirm it.  
  
Note that in general RDS offers a separate set of instance types than EC2, although the naming (db.t2. db.m4, db.r4, etc.) does imply they are based on underlying EC2 instance types.  But the RDS types may have unique characteristics, and should not be considered identical in all regards to the EC2 instances.

the pricing page https://aws.amazon.com/rds/mysql/pricing/ states:  
  
_Amazon RDS T3 DB instances run in Unlimited mode, which means that you will be charged if your average CPU utilization over a rolling 24-hour period exceeds the baseline of the instance. CPU Credits are charged at $0.075 per vCPU-Hour. The CPU Credit pricing is the same for all T3 instance sizes across all regions and is not covered by Reserved Instances._
