apolloconfig/apollo

This system is a comprehensive configuration management platform that provides a centralized backend for managing application configurations across environments. It exposes a RESTful API for creating and updating namespaces, clusters, and items, while enforcing access control, concurrency locking, and audit logging. The architecture supports multiple service discovery mechanisms and includes a web portal for user and consumer management, role-based permissions, and real-time configuration synchronization.

How it got here

2016 · OpenAPI v1 and security hardening

The project introduced a comprehensive OpenAPI v1 interface for external client access, supported by new consumer management, authentication filters, and rate-limiting mechanisms. Concurrently, the codebase was modernized with Spring Boot 3.5.10, JPA repository refactoring, and enhanced security features like namespace locking and access key validation.

2017–2023 · Security, auditability, and caching

This period focused on strengthening the platform's security posture by introducing comprehensive audit logging, robust client authentication, and enhanced user authentication methods like LDAP and OIDC. Concurrently, the team significantly improved system performance and scalability by implementing caching layers and incremental synchronization mechanisms across the config service. The work also expanded administrative capabilities through new UI interfaces for managing access keys, clusters, and third-party consumers.

2024–2026 · authentication and database initialization

This period focused on enhancing the Apollo platform's security and data management capabilities. Key developments included implementing user access token support and servlet filters for OpenAPI authentication, alongside new modules for SQL template conversion and configurable database schema initialization. The work was heavily supported by extensive test coverage, including end-to-end authentication flows and unit tests for various portal and common components.

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 6 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 d95fc18d11 — the exact code this score is about.
  • Scored under rubric rubric-2026.08.19. Score the same commit under that rubric and you get the same number.
