Description

Data is currently exported as CSV by default. Recently, the Parquet export option has also been added to the Azure portal. A parameter to select the file format would therefore be ideal to reduce storage requirements and associated costs.

Potential Terraform Configuration

resource "azurerm_billing_account_cost_management_export" "Daily_MonthToDate" {
  name                         = "MonthToDate"
  billing_account_id           = var.billing_account_id
  recurrence_type              = "Daily"
  recurrence_period_start_date = local.start_time
  recurrence_period_end_date   = "2030-09-20T00:00:00Z"

  export_data_storage_location {
    container_id     = azurerm_storage_container.cost_data.resource_manager_id
    root_folder_path = "daily"
  }

  export_data_options {
    type       = "ActualCost"
    time_frame = "MonthToDate"
    file_format = "Parquet"
  }

  identity = {
    type = "SystemAssigned"
  }

Per the API, the format is a top-level argument and not specific to the definition.

Does it make more sense to include it as a top-level argument in the resource?

resource "azurerm_billing_account_cost_management_export" "Daily_MonthToDate" {
  name                         = "MonthToDate"
  billing_account_id           = var.billing_account_id
  recurrence_type              = "Daily"
  recurrence_period_start_date = local.start_time
  recurrence_period_end_date   = "2030-09-20T00:00:00Z"
  file_format = "Parquet"

  export_data_storage_location {
    container_id     = azurerm_storage_container.cost_data.resource_manager_id
    root_folder_path = "daily"
  }

  export_data_options {
    type       = "ActualCost"
    time_frame = "MonthToDate"
  }

  identity = {
    type = "SystemAssigned"
  }

}

Also, quick note that the current SDK only supports CSV as a valid format type.
