Beyond indexing, several query optimization techniques can significantly improve performance.

CREATE TABLE orders (
order_id SERIAL PRIMARY KEY,
customer_id INTEGER,
order_date DATE,
order_total NUMERIC
) PARTITION BY RANGE (order_date);

CREATE TABLE orders_y2023 PARTITION OF orders
FOR VALUES FROM ('2023-01-01') TO ('2024-01-01');

CREATE TABLE orders_y2024 PARTITION OF orders
FOR VALUES FROM ('2024-01-01') TO ('2025-01-01');

-- Add an index to each partition
CREATE INDEX idx_orders_y2023_customer_id ON orders_y2023 (customer_id);
CREATE INDEX idx_orders_y2024_customer_id ON orders_y2024 (customer_id);
