[Enhancement]: Glue Classifier support for CustomDatatypes in CSV Classifiers

[matschundbrei]

Description

AWS Glue Classifier does support custom datatypes (i.e. a list of datatypes to be forced on a specific column).

In order to work with CSV classifiers in particular and any classifiers downstream in glue workflows, we would have to be able to easily add them to crawlers. The currently supported format of aws_glue_crawler is to pass a list of names to the parameter classifiers.

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

• aws_glue_classifier

Potential Terraform Configuration

resource "aws_glue_classifier" "example" {
  name = "example"

  csv_classifier {
    allow_single_column    = false
    contains_header        = "PRESENT"
    delimiter              = ","
    disable_value_trimming = false
    header                 = ["example1", "example2"]
    quote_symbol           = "'"
    custom_datatypes_used  = true
    custom_datatypes       = ["string", "long" ]
  }
}
