Presto’s superpower is its connector architecture. Let’s set up three common catalogs. Introduction to Presto Setting up Presto Basic Presto
Let’s simulate a real e-commerce dashboard query that aggregates data from MySQL (transactions) and Hive (user profiles).
WITH daily_sales AS (
SELECT
DATE(payment_time) AS sale_date,
user_id,
SUM(amount) AS revenue
FROM mysql.production.payments
WHERE payment_time >= CURRENT_DATE - INTERVAL '7' DAY
GROUP BY 1, 2
)
SELECT
d.sale_date,
u.country,
AVG(d.revenue) AS avg_revenue_per_user,
COUNT(DISTINCT d.user_id) AS active_users
FROM daily_sales d
JOIN hive.user_profiles u ON d.user_id = u.user_id
GROUP BY d.sale_date, u.country
ORDER BY d.sale_date DESC;
In Presto 8.8, this query executes in seconds even if payments has billions of rows, thanks to dynamic filtering and efficient pushdowns.
