Acme Everything Company

This is an example of a Postgres compatable database for Acme Everything Company. It allows you to create customers, a product catalog, and an order system to simulate database activity.

Dependencies

This builds a Go binary that can run on a variety of platforms.

Getting Started

Setup the config file

cp sample-config.yml config.yaml

Edit the config file to reflect your database credentials.

Seed the database with Customers and Products

./Acme --config=config.yaml dbseed

Add Orders

./Acme --config=config.yaml addOrders

All the database operations are tagged in Inisights

Some queries to run

\timing on
select max(total_cost) from orders;

select * from g_columnar_columns;

 SELECT google_columnar_engine_add(relation => 'acme.public.orders', columns => 'order_id,product_id,customer_id,units,total_cost,deleted_at');

Example where the columnar engine comes into play on a small instance

SET google_columnar_engine.enable_columnar_scan=off;
select min(total_cost) from orders /*action='reporting-min',application='cmdline',route='non-columnar' */ ;
SELECT SUM(total_cost) AS total_spent FROM orders WHERE deleted_at is NULL /*action='reporting-min',application='cmdline',route='non-columnar' */;
SET google_columnar_engine.enable_columnar_scan=on;
select min(total_cost) from orders /*action='reporting-min',application='cmdline',route='columnar' */ ;
SELECT SUM(total_cost) AS total_spent FROM orders WHERE deleted_at is NULL /*action='reporting-min',application='cmdline',route='columnar' */;

Then try again with the columnar engine on

SELECT customer_id, SUM(total_cost) AS total_spent FROM orders  WHERE deleted_at is NULL GROUP BY customer_id ORDER BY total_spent DESC LIMIT 10;
