Summary

This PR adds Terraform support for Datadog Datastores and Datastore Items, enabling users to manage key-value data
storage through Infrastructure as Code.

New Resources

• datadog_datastore - Create and manage Datadog datastores with configurable primary keys and access controls
• datadog_datastore_item - Create and manage individual items within a datastore

New Data Sources

• datadog_datastore - Read existing datastore configurations by ID
• datadog_datastore_item - Read existing datastore items by datastore ID and item key

Features

• Full CRUD operations for datastores and datastore items
• Support for custom primary key columns and generation strategies (none, uuid)
• Organization-level access control for datastores
• Import support for existing resources
• Comprehensive documentation and examples

Example Usage

Create a datastore

resource "datadog_datastore" "users" {
name = "users-datastore"
description = "Datastore for user data"
primary_column_name = "id"
primary_key_generation_strategy = "none"
}

Add items to the datastore

resource "datadog_datastore_item" "user1" {
datastore_id = datadog_datastore.users.id
item_key = "user-123"
value = {
id = "user-123"
username = "john_doe"
email = "[email protected]"
}
}

Test Plan

• Added acceptance tests for datadog_datastore resource
• Added acceptance tests for datadog_datastore_item resource
• Tests pass in replay mode with recorded cassettes
• Manual testing with live API

didn't use the generator since this doesn't follow the same pattern but created a config file anyway

[ameesha]

LGTM

[Non-Blocking] Should we also prefix this with datadog_ to align with the item resource below?

Or if it's easier, we can do the reverse: rename datadog_datastore_item to just datastore_item?

[ameesha]

i actually think i'm going to delete these config files all together since i didn't use them for auto generation so they don't map correctly (especially after i made changes)

Ah okay that works
