Description

Vertex AI Search has recently introduced a new feature for data store indexing using sitemaps. This feature needs to be supported during data store creation and thus should be supported by Terraform.

The feature is documented at https://cloud.google.com/generative-ai-app-builder/docs/index-refresh-sitemap

New or Affected Resource(s)

• google_discovery_engine_data_store_sitemap

Potential Terraform Configuration

resource "google_discovery_engine_data_store_sitemap" "example" {
  uri = "https://example.com/sitemap.xml"
}

Note: This looks to be a fine-grained resource since it relies on a siteSearchEngine as the parent parameter which is obtained from a method found in the datastore resource called getSiteSearchEngine

Is there any progress on this? I'd be glad to implement it but need some guidance on how the resources should be created.
