tapmodo / influx-collector.js

Last active October 29, 2015 02:50

This is a first stab at a batch uploader for InfluxDB. It seems to work. If you wanted to use this for any other queue batching operation, you could overload the write() and _send() methods...

	var _ = require('lodash');
	var debug = require('debug')('influx:batch');

	var SeriesWriter = function(db,options){
	this.db = db;
	this.setOptions(options);
	this.sending = false;
	this.timer = null;
	this.queue = [];
	};

tapmodo / map_and_filter.js

Created October 22, 2014 23:41

map and filter functions

	// map function
	function array_map(arr,fn) {
	var rv = [];

	for(var i=0, l=arr.length; i<l; i++)
	rv.push(fn(arr[i]));

	return rv;
	};

tapmodo / polyfills.js

Created October 22, 2014 23:24

	// Array.map polyfill
	if (Array.prototype.map === undefined) {
	Array.prototype.map = function(fn) {
	var rv = [];

	for(var i=0, l=this.length; i<l; i++)
	rv.push(fn(this[i]));

	return rv;
