From what I can see in the management console, OR1 and Im4gn instance types are apparently supported in the Multi-AZ with standby as well.
I selected "Domain with standby" and was able to select both OR1 and Im4gn. I also confirmed that t3 cannot be selected for "Domain with standby", and the t3 can be selected for "Domain without standby" (with the "Include previous generation instance types" toggle).
(Note that I did not actually create the domain.)
Thanks @go-to-k! |

Issue # (if applicable)
Related with #26026
Reason for this change
#26082 enabled Multi-AZ with Standby by default, but deployment fails if we use t3 instance type, because it does not support the feature. To fail fast, this PR adds validation on synth time.
Description of changes
If the instance type of data node or master node is t3, throws an error.
I also considered to automatically set
multiAzWithStandbyEnabled: false
if we detect any t3 instance type, but it would introduce unwanted behavior e.g. in the below case:so we just throw an error.
Description of how you validated changes
Added some unit tests.
I also confirmed that it results in deployment error if we try to deploy with t3 instance type &
multiAzWithStandbyEnabled : true
for both data node and master node.Checklist
