This repo was created as suppliment to the HashiTalks 2021 "Automating Snowflake" demonstrate the use of Terraform to create a S3 Snowflake integration.

• Snowflake account - Free account available
• Terraform Cloud - Free account available
• AWS - Free tier availale account available\

You will need to set up a Terraform User for Snowflake to use. Here is an example SQL statement to use:

USE ROLE ACCOUNTADMIN;
CREATE USER TERRAFORM PASSWORD = '********' DEFAULT_ROLE = "ACCOUNTADMIN" MUST_CHANGE_PASSWORD = FALSE;
GRANT ROLE "ACCOUNTADMIN" TO USER Terraform;

Next create a workspace in Terraform Cloud and add the below Environment variables

SNOWFLAKE_ACCOUNT = <FROM YOUR NEWLY CREATED ACCOUNT>
SNOWFLAKE_PASSWORD = <PASSWORD FROM THE ACCOUNT CREATED ABOVE>
SNOWFLAKE_USER = TERRAFORM
AWS_ACCESS_KEY_ID = <FROM YOUR AWS ACCOUNT>
AWS_SECRET_ACCESS_KEY = <FROM YOUR AWS ACCOUNT>

Update the Terraform workspace to match the workspace created elg.

terraform {
  ....
  backend "remote" {
    organization = "<ADD YOUR ORG HERE>"

    workspaces {
      name = "<ADD YOUR WORKSPACE HERE>"
    }
  }

• Create an S3 Bucket called hashitalks-dev-snowflake-demoin the same region as your Snowflake account

• Create a folder for where your data is going to land called hello-world

• To provision type:

terraform apply

• Confirm connection between S3 and Snowflake by typing in a Snowflake Worksheet

LIST @STG_LANDING_HELLO_WORLD

• Confirm that no data exists in the new database

SELECT * FROM "SNOWFLAKE_HELLO_WORLD"."RAW"."HELLO_WORLD"

This should should not error and return empty

• In AWS, drop the contents of ./examples into the S3 bucket/hello-world path

• Go back to Snowflake and run the below query again to see if data has been pulled to Snowflake from S3

SELECT * FROM "SNOWFLAKE_HELLO_WORLD"."RAW"."HELLO_WORLD"
