如何在node.js中流水线到Redis? [英] How to pipeline in node.js to redis?

问题描述

我有很多数据要插入(SET \ INCR)到Redis DB，所以我正在寻找管道 \ <通过 node.js a href ="http://redis.io/topics/mass-insert">大量插入.

I have lot's of data to insert (SET \ INCR) to redis DB, so I'm looking for pipeline \ mass insertion through node.js.

我在node.js中找不到任何好的示例/API，因此任何帮助都将非常有用！

I couldn't find any good example/ API for doing so in node.js, so any help would be great!

推荐答案

是的，我必须同意缺少示例，但是我设法创建了一个流，在该流上我批量发送了多个插入命令.

Yes, I must agree that there is lack of examples for that but I managed to create the stream on which I sent several insert commands in batch.

您应该安装用于redis流的模块:

You should install module for redis stream:

npm install redis-stream

这是您使用流的方式:

var redis = require('redis-stream'),
    client = new redis(6379, '127.0.0.1');

// Open stream
var stream = client.stream();

// Example of setting 10000 records
for(var record = 0; record < 10000; record++) {

    // Command is an array of arguments:
    var command = ['set', 'key' + record, 'value'];  

    // Send command to stream, but parse it before
    stream.redis.write( redis.parse(command) );
}

// Create event when stream is closed
stream.on('close', function () {
    console.log('Completed!');

    // Here you can create stream for reading results or similar
});

// Close the stream after batch insert
stream.end();

此外，您可以根据需要创建许多流，并随时根据需要打开/关闭它们.

Also, you can create as many streams as you want and open/close them as you want at any time.

在几个示例 /master/example"rel =" noreferrer>重新分发流节点模块

There are several examples of using redis stream in node.js on redis-stream node module
