Database DevOps

Version Control and Migration

Flyway Implementation

-- V1__initial_schema.sql
CREATE TABLE users (
    id SERIAL PRIMARY KEY,
    email VARCHAR(255) NOT NULL UNIQUE,
    created_at TIMESTAMPTZ DEFAULT CURRENT_TIMESTAMP
);

-- V2__add_user_status.sql
ALTER TABLE users ADD COLUMN status VARCHAR(50) DEFAULT 'active';
