Workload framework

dbworkload

dbworkload is a Python utility for creating and running bespoke database workload scripts.

It is designed for cases where you want full control over the workload logic, but do not want to rebuild the surrounding execution machinery every time. You write the workload as a Python class; dbworkload handles the operational pieces around it, such as concurrency, process/thread execution, run duration, iteration limits, scheduling, metrics collection, and result output.

Why use it?

Database workloads are often highly specific: the order of transactions, the statements inside each transaction, the shape of generated data, and the way that data changes over time all matter. dbworkload keeps that logic in your hands while providing a reusable runner around it.

With dbworkload, you can:

• model realistic application flows as Python code;
• control which transactions run, in which order, and with which data;
• scale execution across configurable processes, threads, and connections;
• run workloads for a fixed duration or number of iterations;
• collect and export execution statistics;
• target different databases by installing the driver extras you need.

How it works

A workload is a Python class that defines how connections are set up and what each execution loop should do. At runtime, dbworkload imports that class, starts the requested level of concurrency, opens database connections, executes the workload loop, aggregates stats, and stops when the configured limit is reached or the run is interrupted.

This split keeps the workload script focused on database behavior while the runner handles the repeatable mechanics of executing it.

Documentation

The README is only a short introduction. For installation, examples, CLI reference, supported drivers, and workload authoring details, visit the official documentation:

MCP Server

dbworkload also ships an optional MCP server for AI coding agents. It exposes workload authoring guidance and a one-iteration dry-run tool so agents can generate, validate, and repair workload files locally.

See dbworkload/mcp/README.md for installation and client configuration examples.
