...Its examples emphasize understanding core design ideas rather than relying on finished frameworks. The repository includes Gee, a Gin-like web framework with routing, middleware, templates, and panic recovery. GeeCache demonstrates LRU caching, concurrency, consistent hashing, distributed nodes, single-flight protection, and Protobuf communication. GeeORM covers mapping, queries, hooks, transactions, and migrations. GeeRPC builds on net/rpc with concurrent clients, timeouts, HTTP transport, load balancing, registration, and service discovery.

...We looked around for a solution, but we couldn’t find a great one. We then tried using a sharded map, with shard eviction to release memory, which caused us memory issues. We then repurposed Groupcache’s LRU, using mutex locks for thread safety. After having it around for a year, we noticed that the cache suffered from severe contention. A commit to remove that cache caused our query latency to dramatically improve by 5-10x. In essence, our cache was slowing us down! We concluded that the concurrent cache story in Go is broken and must be fixed. ...
