如何确保在ElasticSearch Bonsai Free实例中使用Firebase FlashLight为每个对象建立索引

如果您要索引一堆数据，则Flashlight应用程序将要求ES动态索引每个对象，而没有任何资源访问限制。您必须使用信号量来控制/限制对该共享资源的访问。

安装信号量库

npm i --save semaphore

编辑

PathMonitor.js

PathMonitor.prototype = {    _init: function () {        this.sem = require('semaphore')(1);        this.addMonitor = this.ref.on('child_added', this._process.bind(this, this._childAdded));        this.changeMonitor = this.ref.on('child_changed', this._process.bind(this, this._childChanged));        this.removeMonitor = this.ref.on('child_removed', this._process.bind(this, this._childRemoved));    },    ...    _index: function (key, data, callback) {        var that = this;        that.sem.take(function () { that.esc.index({     index: that.index,     type : that.type,     id   : key,     body : data }, function (error, response) {     that.sem.leave();     if (callback) {         callback(error, response);     } }.bind(that));        });    },    ...}

对于付费计划，可能不需要这样做。
