[Enhancement]: Data Source: aws_redshift_cluster New Attribute "number_of_slices"

[simonB2020]

Description

Request that a new attribute provides the number of slices in a cluster.

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

Data Source: aws_redshift_cluster

Potential Terraform Configuration

data "aws_redshift_cluster" "example" {
  cluster_identifier = "example-cluster"
}

resource "aws_glue_job" "my_glue_job" {
  name  = "my_glue_job"
  default_arguments = {
    "--cluster-slices" = data.aws_redshift_cluster.example.number_of_slices
 }
}

References

AWS Redshift documentation specifies that a developer (e.g of an AWS Glue Job) should split files into a multiple of the number of slices in the target Redshift cluster.

Hence we would need to obtain this value in order to pass to Glue Jobs or Lambda functions provisioned by Terraform.

https://docs.aws.amazon.com/redshift/latest/dg/t_splitting-data-files.html

"Split your data into files so that the number of files is a multiple of the number of slices in your cluster"

Would you like to implement a fix?
