Ristretto is a high-performance in-memory cache and concurrent key-value store for Go applications. It provides a thread-safe memory store that manages strict memory bounds and employs probabilistic set filters to reduce lookup overhead. The system is distinguished by an admission-policy cache that utilizes frequency sketches and cost-based eviction to maximize hit ratios. It minimizes contention and improves throughput through the use of striped ring buffers and concurrent map sharding. The project covers a broad range of data management capabilities, including time-based expiration, item f

DiskLruCache is a disk-backed key-value cache library for Android and Java environments that stores data on the filesystem within a configurable byte limit. It uses a least-recently-used (LRU) eviction policy to automatically remove old entries when the cache exceeds its allocated size, and maintains a journal file to reconstruct its in-memory state after a process restart. The cache provides atomic write operations that first write new data to a temporary file before atomically renaming it, preventing partial or corrupted reads during concurrent access. It returns frozen snapshots of cache e

webfunny_monitor is an open-source frontend monitoring and analytics platform that tracks page load performance, JavaScript errors, and user behavior. It serves as a comprehensive tool for measuring page load speed, API response times, client-side errors, and custom user events, with real-time dashboards that stream aggregated metrics via WebSocket for sub-second updates. The project distinguishes itself through its architectural approach: events are collected asynchronously via lightweight HTTP beacons and batched before transmission, while a memory-bounded local storage buffer ensures relia

This is a thread-safe in-memory cache library for Go that automatically evicts the least recently used items when capacity is reached. It provides a fixed-size memory cache designed to maintain a constant memory footprint by removing the oldest entries as new data arrives. The system includes an eviction manager that executes custom callbacks when entries are purged to facilitate resource cleanup. It also supports time-based expiration, allowing for the automatic removal of items after a specified time-to-live duration. The library covers general caching capabilities including cache inspecti
