package main
// This is a basic example of running an nsqd instance embedded. It creates
// and runs an nsqd with all of the default options, and then produces
// and consumes a single message. You are probably better off running a
// standalone instance, but embedding it can simpllify deployment.
// See https://github.com/bitly/nsq/blob/master/nsqd/options.go and
// https://github.com/bitly/nsq/blob/master/apps/nsqd/nsqd.go for
// more details on how to configure an embedded nsqd instance.

Distributed Read-Write Mutex in Go

The default Go implementation of sync.RWMutex does not scale well to multiple cores, as all readers contend on the same memory location when they all try to atomically increment it. This gist explores an n-way RWMutex, also known as a "big reader" lock, which gives each CPU core its own RWMutex. Readers take only a read lock local to their core, whereas writers must take all locks in order.

Here are some things you can do with Gists in GistBox.
// Use Gists to store code you would like to remember later on
console.log(window); // log the "window" object to the console
