Cloud Native Utils

A collection of high-performance, modular utilities for enhancing testing, transactional consistency, efficiency, security, and stability in cloud-native Go applications.

Module Features

• assert: Provides tools for testing, including utility functions to assert value equality and simplify debugging during development.
• consistency: Implements transactional log management with Event and EventType abstractions, and supports file-based persistence using JsonFileLogger for reliable data storage.
• efficiency: Offers utilities for generating read-only channels, merging and splitting streams, concurrent processing of channel items, and partitioning key-value stores using shards for scalability and performance.
• extensibility: Dynamically load external Go plugins using LoadPlugin. Just provide a symbol name (e.g., a function) to integrate new features on-the-fly—no rebuilds or redeploys required.
• security: Includes encryption and decryption with AES-GCM, secure key generation, HMAC hashing, bcrypt-based password handling, and a preconfigured secure HTTP(S) server with liveness and readiness probes for robust application security.
• service: Enhances service orchestration by grouping related functionality, wrapping functions to support context-aware execution and add lifecycle-oriented functionality like signal handling in cloud-native environments.
• stability: Ensures service robustness with mechanisms like circuit breakers, retries for transient failures, throttling for rate limiting, debounce for execution control, and timeouts for enforcing execution limits.
• templating: Provides an Engine for managing templates stored in an embedded filesystem. Use Parse to load multiple templates (via glob patterns), and Render to execute them with custom data.
