Is this the proper way to backpressure redis-drain? When the value for each key is 4kb then it throws JS Memory Allocation error.

redisload.js

var redis = require("redis"),
    fs = require("fs"),
    client = redis.createClient();

var glCount = 150000 ;
var j = glCount;
var curCount = 0;
var startTime = new Date;
var i = 0;

client.on("drain", function(err){
	console.log('drain event emitted');
	load();
	console.log(client.command_queue.length);
		
});
load();

var offlineq = 1000;
function load(){
for(;i<glCount;i++){

		if(client.command_queue.length > 1000){
			
			break;
		}
		client.set("BM_" + i + "ABCDEFGHIJKLMNOPQRSTUVWXYZ","testValue",function(err){	
			curCount++;
			if (glCount == 0){
				var endTime = new Date;
		
				console.log("Done Loading the keys took time: " + (endTime - startTime) + "ms");
				client.end();
			}
		});

		
	} 
}

setInterval(function(){console.log(client.command_queue.length);}, 1000);
