Expensive JOINs
Multi-table joins that take seconds, served in milliseconds. The results are pre-computed and kept fresh — your queries stay exactly the same, they just arrive faster.
SELECT * FROM orders
JOIN users ON …
JOIN products ON …
Missing Indexes
Slow filters and sorts, identified and fixed automatically. The right index for your actual query patterns, created without you lifting a finger.
SELECT * FROM events
WHERE status = 'active'
AND created_at > …
Heavy GROUP BY
Dashboard queries that recompute on every page load, served instantly. The aggregation happens once — every subsequent request reads the answer directly.
SELECT region,
SUM(total)
FROM orders
GROUP BY region
Slow Subqueries
Subqueries that re-execute for every row, replaced with instant lookups. The expensive work is done once and the results are ready when your query arrives.
SELECT * FROM users
WHERE id IN (
SELECT user_id
FROM orders …
)
Search
Search your data by meaning, by sound, or by any fragment of a string — all fast, all indexed automatically. No separate search engine to deploy, no data pipeline to keep in sync.
SELECT * FROM articles
WHERE to_tsvector('english', body)
@@ to_tsquery('search terms')
Expensive CTEs
Reporting queries that rebuild the same intermediate results on every request. The heavy lifting is done once — your reports read from pre-computed answers.
WITH monthly AS (
SELECT …
FROM orders
GROUP BY month
)
SELECT * FROM monthly …
N+1 Queries
The same query repeated fifty times in a single request — detected automatically, collapsed into one round-trip, and served from cache for the rest.
-- repeated per row:
SELECT * FROM authors
WHERE id = $1
Connection Pooling
Two hundred application connections, twenty database connections, zero configuration. Built into the proxy — nothing else to deploy or manage.
-- 200 app connections
-- 20 database connections
-- zero configuration
Read Replicas
Reads route to your replicas automatically. Writes go to the primary. Your application sees its own writes immediately, even while replicas catch up.
-- reads → replica
SELECT * FROM orders …
-- writes → primary
INSERT INTO orders …
