[Enhancement]: r/aws_dynamodb_table: Support On-Demand Throughput

[jar-b]

Description

The CreateTable and UpdateTable APIs now support configuration of on-demand throughput for tables and global secondary indexes. The aws_dynamodb_table resource should add corresponding arguments. Overrides can also be applied to replication

• Add on_demand_throughput block argument, containing max_read_request_units and max_write_request_units arguments. r/aws_dynamodb_table: add on_demand_throughput attribute  #37799
• Add the ability to configure the same options on global secondary indexes (ie. the same on_demand_throughput argument, but nested inside the global_secondary_index block).
• Assess whether the import_table and replica blocks can incorporate on_demand_throughput_override configurations.
• Add acceptance tests for both cases.
• Update registry documentation.

Affected Resource(s) and/or Data Source(s)

• aws_dynamodb_table

Potential Terraform Configuration

resource "aws_dynamodb_table" "example" {
  ### other configuration ###

  on_demand_throughput {
    max_read_request_units  = 1
    max_write_request_units = 1
  }

  global_secondary_index {
    on_demand_throughput {
      max_read_request_units  = 2
      max_write_request_units = 2
    }
  }
}

We need this feature asap. Any insights into when will this be prioritised?

Worth noting this is in AWS's Cloud Control provider, as an alternative in the meantime:
