qg

Ruby Que implementation in Go. This library is almost a fork of que-go, the great work of bgentry.

Why created

First of all, Que, and it's Go port que-go are really great libraries, which can simplify small to mid scale application with some sort of asynchronous tasks/jobs by avoiding to add another moving part if you are already using PostgreSQL as main RDBMS. However, as I use que-go to develop my application written in Go, there are some functionalities that que-go doesn't provide. The following is an list of functionalities I'm going to add to qg.

• database/sql compatible version of enqueue functions so that many other database libraries can work with it.
• Transaction can be injected to a Job to make WorkFunc tests much easier.
• Customizable Job.Delete(), Job.Error() to give more flexibility.
• Synchronous execution option in Client.Enqueue and Client.EnqueueInTx for easy development.
• Better logger interface to be able to switch whatever loggers developers want.

This library is still under heavy development, and might significantly change APIs.

Test

create user qgtest;
create database qgtest owner qgtest;

$ psql -U qgtest -d qgtest -f schema.sql

go test -v
