groupcache
A distributed caching and cache-filling library for Go, designed as a replacement for memcached clusters.
What is groupcache?
groupcache is a distributed caching and cache-filling library written in Go, designed to replace memcached clusters in many scenarios. It coordinates cache fills to prevent thundering herd problems and automatically mirrors hot items across processes. The library acts as both client and server, forming a peer-to-peer cache network without requiring separate cache servers.
Go developers building distributed systems that require efficient, coordinated caching to reduce database load and improve performance. It's particularly useful for teams managing memcached deployments who want to simplify infrastructure.
Developers choose groupcache because it eliminates the operational overhead of separate cache servers while providing intelligent cache-filling coordination that prevents thundering herd outages. Its peer-to-peer architecture and automatic hotspot mitigation offer better reliability and performance for read-heavy workloads compared to traditional memcached setups.
