Tutorial: introdução à arquitetura de alto desempenho do Snowpipe Streaming SDK¶

-- 1. Create a dedicated role and user (Run with a highly-privileged role)
CREATE OR REPLACE USER MY_USER;
CREATE ROLE IF NOT EXISTS MY_ROLE;
GRANT ROLE MY_ROLE TO USER MY_USER;

-- 2. Set the public key for key-pair authentication
-- NOTE: Replace 'YOUR_FORMATTED_PUBLIC_KEY' with the output of the PUBK variable from the key generation step.
ALTER USER MY_USER SET RSA_PUBLIC_KEY='YOUR_FORMATTED_PUBLIC_KEY';

-- 3. Set the default role (Recommended)
ALTER USER MY_USER SET DEFAULT_ROLE=MY_ROLE;

-- 4. Switch to the new role and create objects
USE ROLE MY_ROLE;
-- NOTE: You may also need to run USE WAREHOUSE YOUR_WH; here if a default warehouse isn't set.

-- Create database and schema
CREATE OR REPLACE DATABASE MY_DATABASE;
CREATE OR REPLACE SCHEMA MY_SCHEMA;

-- Create a target table
CREATE OR REPLACE TABLE MY_TABLE (
    data VARIANT,
    c1 NUMBER,
    c2 STRING
);

-- Create PIPE object for streaming ingestion
CREATE OR REPLACE PIPE MY_PIPE
AS COPY INTO MY_TABLE FROM (SELECT $1, $1:c1, $1:ts FROM TABLE(DATA_SOURCE(TYPE => 'STREAMING')));


-- 5. Configure authentication policy (Optional, but recommended for explicit control)
CREATE OR REPLACE AUTHENTICATION POLICY testing_auth_policy
  AUTHENTICATION_METHODS = ('KEYPAIR')
  CLIENT_TYPES = ('DRIVERS');

-- Apply authentication policy (if created)
ALTER USER MY_USER SET AUTHENTICATION POLICY testing_auth_policy;
