When comparing pq and hashmap you can also consider the following projects:

haxmap - Fastest and most memory efficient golang concurrent hashmap

go-left-right - A faster RWLock primitive in Go, 2-3 times faster than RWMutex. A Go implementation of concurrency control algorithm in paper <Left-Right - A Concurrency Control Technique with Wait-Free Population Oblivious Reads>

sonic - A blazingly fast JSON serializing & deserializing library

xxHash - Pure Go implementation of xxHash (32 and 64 bits versions)

query-json - Faster, simpler and more portable implementation of `jq` in Reason


gofx - 🐾 fx-like command-line JSON processing tool
