DynamoDB/sync

This package is designed to emulate the behaviour of pkg/sync on top of Amazon's DynamoDB. If you need a distributed locking mechanism, consider using this package and DynamoDB before standing up paxos or Zookeeper.

Dependency Management

This project uses Glide to manage it's dependencies, and does not commit the vendor directory. As a result this is not go get installable, please refer to the Glide docs for Glide install instructions, and make sure to glide install to create a vendor directory before attempting to build against this repo.

Usage

Create a DynamoDB table named Locks.

$ export AWS_ACCESS_KEY=access
$ export AWS_SECRET_KEY=secret

// ./main.go

package main

import(
	"time"
	"github.com/zencoder/ddbsync"
)

func main() {
	m := new(ddbsync.Mutex)
	m.Name = "some-name"
	m.TTL = int64(10 * time.Second)
	m.Lock()
	defer m.Unlock()
	// do important work here
	return
}
