Caused by: Overly Complex Queries

On Tues, 2023-02-21 14:30 the server experienced a catastrophic database failure due to a query that was way too complex.

The offending query was:

SELECT * FROM customers WHERE customer_name LIKE 'John' AND order_date BETWEEN '2022-01-01' AND '2022-01-31' AND order_total > 1000 AND order_status IN ('pending', 'shipped', 'cancelled')

This query, while seemingly harmless, caused the database to spiral out of control, consuming all available resources and bringing the entire system to its knees.
