xk6-sql VS Knex

xk6-sql

In this tutorial, let’s explore how to load test a database using the xk6-sql extension. For simplicity, the tests will be executed against a local SQLite3 server but the extension supports the following RDBMS databases:

Knex.js

AdonisJS core team has created/maintains Lucid. It is a SQL query builder, and an Active Record ORM built on top of Knex.

Now, why not use an ORM? I've seen performance issues too many times with ORMs. I prefer writing my own SQL to avoid surprises. After all, I know the database schema and writing code for a specific purpose very often leads to better performance than generic code. ORMs have to support all kinds of database schemas. I only have to support mine. Having successfully used Knex.js in NodeJS (a popular query builder) in the past, I know writing SQL queries myself is not hard and provides very good performance.

Given the dynamic nature of the schema, we employ Knex, a query builder, for database access.

This article will be focused on a security issue that I found in Knex and how to mitigate it, but I'll also talk briefly about the social aspects of this problem.

SQL is an old, irregular language to work with, but it is better known than HCL and SQL already has it's own Pulumi/CDK in the form of every ORM with introspection (like Javascript's Prisma, Python's Django, Go's XO etc) and QueryBuilder (LINQ, Knex, etc) in whatever programming language you prefer. You probably already know it.
