Carrot Cache: High-Performance, SSD-Friendly Caching Library for Java

10 months ago

Carrot Cache is a high-performance, SSD-friendly caching library for Java, now open-sourced under Apache 2.0.
It offers advanced compression, smart data tiering, and SSD-friendly design, making it efficient for large-scale workloads.
Key features include enhanced memory efficiency (up to 5x savings), true data tiering (RAM + SSD), and ultra-fast snapshots (150x faster than Redis).
Supports per-object expiration, minimal metadata overhead (8–14 bytes per object), and sequential writes for SSD longevity.
Benchmarks show Carrot Cache is 2–5.9x more memory-efficient than Caffeine and EHCache with client-side compression.
Uses 'Herd Compression' to optimize data patterns dynamically for maximum efficiency.
Open-source benefits include full GitHub access, community contributions, and easy integration with existing systems.
Future plans include expanding features and integrations, like Spring Boot support.
