软件介绍
Martinet 是分布式任务管理工具。
Martinet 数据库后端，基于 zeroMQ 的分布式任务管理系统。Martinet 可以使用任意的 sequelize.js 兼容的数据库（默认是 SQLite）。
Martinet 使用 push-pull 管理模式来确保在分布式的环境下高效的运行。
安装
npm install martinet
使用
Martinet 包括两个部分： Martinet 对象，处理调度和调度任务； Worker 对象，接受任务和定义。
Martinet
安装
var Martinet = require('martinet');
var martinet = new Martinet();
// Martinet allows you to create multiple workers
// so that you can keep worker code in separate
// logical
modules.martinet.addWorker('WORKER_NAME_1', 'WORKER_PORT_1');
martinet.addWorker('WORKER_NAME_2', 'WORKER_PORT_2');
创建任务
martinet.execute({
worker: 'WORKER_NAME',
name: 'task_name',
description: 'Do a thing' // Used in the backend so it's easier to lookup tasks later
}, args);
// args JSON object of named arguments, so like
// {
// thing_id: 1
// }
//
// this object gets serialized and passed to the Worker
//
martinet.schedule('in 20 minutes', {
worker: 'WORKER_NAME',
name: 'task_name',
description: 'Do a thing in 20 minutes'}, args);
martinet.every('30 minutes', {
worker: 'WORKER_NAME',
name: 'task_name',
description: 'Do a thing every half hour',
run_at: 'midnight' // optional time to start the recurring task}, args);
Workers
安装
var MartinetWorker = require('martinet').Worker;var WORKER_PORT = 3000;var worker = new MartinetWorker(WORKER_PORT, {
martinet_url: '127.0.0.1',
martinet_port: '8089'});
定义任务
worker.on('task_name', function(taskId, data, callback) {
// do a thing.
// if it's successful, callback(),
// if there's an error, callback(err)});
端口
Martinet 的 pull socket 监听端口：
var Martinet = require('martinet');var options = {
port: 8009};var martinet = new Martinet(options);
DB
后端数据库的连接信息，使用 sequelize.js 选项。
默认：
var Martinet = require('martinet');var options = {
db: {
database: 'martinet-db',
username: process.env.USER,
password: null,
options: {
dialect: 'sqlite',
storage: 'martinet.db',
logging: false,
omitNull: true
},
sync: true
}};var martinet = new Martinet(options);
使用 postgres：
var Martinet = require('martinet');var options = {
db: {
database: 'martinet-db',
username: process.env.USER,
password: null,
options: {
dialect: 'postgres',
port: 5432,
host: 'database.host'
logging: false,
omitNull: true
},
sync: true
}};var martinet = new Martinet(options);
