Deploying power-of From Cloud Storage

You'll need the following information to do this:

• The path to the compiled Wasm module (we'll use ./power.wasm below, but for the Rust example, you should use located in target/wasm32-wasi/debug/power.wasm instead)
• The path to the WIT file
• Your cloud storage credentials and path (we'll assume an S3 bucket called wasm-modules).

From your work directory, you'll need to upload your WIT (./power.wit) and compiled Wasm (.wasm) files to a bucket to the wasm-modules S3 bucket.

Now, connect to the database from your SQL client and run the following statement to pull the module from S3 into the wasm_tutorial database:

CREATE FUNCTION power_of AS WASM 
FROM S3 'wasm-modules/power.wasm'
    CREDENTIALS '{
        "aws_access_key_id": "ASIAZPIKLSJ3HM7FKAUB",
        "aws_secret_access_key": FwoGZXIvYXdzEL3fv [...]"
    }'
    CONFIG '{"region": "us-east-1"}'
WITH WIT FROM S3 'wasm-modules/power.wit'
    CREDENTIALS '{
        "aws_access_key_id": "ASIAZPIKLSJ3HM7FKAUB", 
        "aws_secret_access_key": FwoGZXIvYXdzEL3fv [...]"
    }' 
    CONFIG '{"region": "us-east-1"}';

If the UDF has been created successfully, you will see something like:

Query OK, 1 row affected (0.029 sec)

Finally, we're ready to run the UDF!
