ristretto
A high-performance, concurrent cache library for Go with cost-based eviction and excellent hit ratios.
What is ristretto?
Ristretto is a high-performance, concurrent cache library written in Go, designed for memory-bound caching scenarios. It solves the problem of efficiently managing cache eviction and admission to maximize hit ratios and throughput, particularly in high-concurrency applications like databases and search engines. Its unique combination of TinyLFU admission and SampledLFU eviction policies ensures excellent performance across various workloads.
Go developers building high-performance applications that require efficient in-memory caching, such as database systems (e.g., Dgraph, Badger), search engines, or any service needing low-latency data access with high concurrency.
Developers choose Ristretto for its best-in-class hit ratios, fully concurrent design, and cost-based eviction, which together provide superior performance compared to other Go cache libraries. Its focus on correctness and simplicity, coupled with optional metrics, makes it a reliable choice for production systems.
