Expected Behavior

When I change global_secondary_index.read_capacity from 10 -> 60, terraform plan should show a change to the read_capacity for my global secondary index

Actual Behavior

When I change global_secondary_index.read_capacity from 10 -> 60, no changes are reported with terraform plan

Steps to Reproduce

Please list the full steps required to reproduce the issue, for example:

1. Create a dynamo db table with terraform
   -- Set the read/write capacity for a global secondary index (not the table level read/write capacity) to 10 each
2. terraform apply to create the table in AWS
3. Change your terraform code to set the global secondary index read/write capacity to 60 each
4. terraform plan to see no changes to the global secondary index capacities

Additional Context

I'm using a dynamic block for the global_secondary_index, and a variable block to populate it

Providers:

• AWS 2.21.1 (tried with 2.22.0 too)
• External 1.2.0
• null 2.1.2
• random 2.1.2
• template 2.1.2

^ This should be possible, according to the API docs.

This also affects changes to the primary sort keys. When changing from a string type to a Number for example. The change is ignored and results in "No Changes"

Expected behavior in this case would be a destroy/create operation on the entire table. I felt like this was related so I'm posting this here
