How it got here

2016 · Cachex library introduction and refactoring

This period marks the introduction of the Cachex in-memory cache library, featuring a comprehensive public API backed by ETS. The codebase underwent significant architectural refactoring to separate concerns into dedicated modules for actions, hooks, and routing, while simultaneously establishing a robust test suite to validate the new functionality.

2017 · Service-based architecture refactoring

The codebase underwent a significant architectural shift to a service-based model, replacing a monolithic process structure with dedicated GenServer processes for cache management, locking, and notifications. This period also introduced a new specification validator to enforce runtime type checking and added comprehensive test coverage for these new components.

2018–2024 · Routing and limit policy expansion

This period focused on expanding the library's capabilities by introducing four new cache routing strategies and three cache limit policies. The work included implementing the routing and limit modules, adding comprehensive test coverage, and updating the benchmarking suite to use the Benchee library.

About this page

  • The description of this project is derived from its own commit history, not from its README.
  • The score is its highest published measurement, taken on 1 August 2026 at a pinned commit. It is not a live figure and does not change until the project is measured again.
  • Measured at commit 44ac7e445b — the exact code this score is about.
  • Scored under rubric rubric-2026.08.18. Score the same commit under that rubric and you get the same number.
