DZone MongoDB Reference Card

By on 2013/02/04 in education, general, MongoDB

As developers we’re always appreciative of documentation that lets us absorb a lot of detailed information as quickly as possible. While nothing can replace a detailed reading of the core MongoDB documentation from 10gen, a few pages of pithy reminders can make operational life a lot easier.

MongoLab sponsored the recent DZone reference card for MongoDB. Here’s a little snippet below. Download the rest of it here http://refcardz.dzone.com/refcardz/mongodb. (registration with DZone required)

Thanks to Kristina Chodorow and the 10gen crew for a nice reference card and to the folks at DZone for producing it!

UPDATE 2013-02-06: added note saying that DZone requires registration

Automated Slow Query Analysis: Dex recorded presentation from MongoSV 2012

Automated Slow Query Analysis: Dex the Index Robot

On December 4th, MongoLab engineer Eric Sedor presented about “Automated Slow Query Analysis: Dex the Index Robot” at MongoSV 2012, an annual one-day conference in Silicon Valley, CA, dedicated to the open source, non-relational database MongoDB.

A well-indexed query improves performance by several orders of magnitude. The trick is to identify an ideal set of indexes for a particular use case. Even for experts, hand-crawling MongoDB log for slow queries is a laborious process. Introducing Dex: an open-source automated tool for analyzing the slow query log or system.profile collection. Dex’s primary author Eric Sedor demonstrates Dex’s usage and elaborates on indexing topics from the basic to the advanced. Includes how to pick indexes in an elegant, practical way. You learn how Dex categorizes slow queries and recommends indexes to help keep your application running smoothly. Eric is an engineer at MongoLab, cloud-hoster of MongoDB, where Dex is used daily to optimize customer indexes.

Check out the recording below and please be sure to check out 10gen’s page for the presentation which has links to Speaker Deck slides and an alternate video link.

Here’s Dex’s github page, and the latest version (0.5) announcement

MongoLab Discount for JS.everywhere() 2012

By on 2012/10/08 in announcement, events, general, JSON, MongoDB

MongoLab is happy to be sponsoring the JS.everywhere() conference in Silicon Valley at the end of October. If you’re interested in joining us, please use this discount code on the registration page: “mongolabJS”.  You’ll get 50% discount on attendance. We are looking forward to seeing you there.

MongoDB’s native support for JSON of course makes it a natural fit to work with Javascript.  Javascript’s growing popularity beyond browser clients is driving the need for a scalable JSON persistence layer.  Having that cloud persistence layer at MongoLab, we get to see many interesting new projects in enterprises large and small.  So we’re excited to be reaching out to meet new users.

Details on our events page:

Nodestack

By on 2012/09/27 in education, events, general, JSON, MongoDB, partnerships, trends


We’re excited be part of the Oct 17 Nodestack.org online conference with Joyent, Clock Ltd, 10gen, and Nodejitsu.

What is Nodestack?

If you’re a Web developer you may have felt the same thing in the last year or so: Javascript is winning. More precisely, Joyent’s Node.js, supported by 10gen’s JSON-centric MongoDB database for persistence is winning. And by using SmartOS as the host for Node.js, Joyent offers the inspectability, performance, and debuggability capabilities of DTrace and ZFS to Nodestack.

Parochially, I’ve included a Google Trends widget above comparing “node”, “ruby”, and “java” when searched with “mongodb”. As of this writing, “node” had just crossed “ruby”s trend line and was headed up to challenge “java”.

Why Nodestack?

There are many reasons why Nodestack is emerging as a leading developer choice, including:

  • developer familiarity with Javascript from front-end browser domains
  • the battle-tested underlying Google V8 Javascript engine for high performance
  • a harmonious non-blocking asynchronous IO environment resulting in efficient CPU utilization
  • good fitness for demanding near real-time dynamic web and mobile applications
  • effortless JSON-awareness across the stack means fewer developer cycles wasted on data translation
  • a well-supported package management system with growing library of components for basic and advanced needs
  • a deep-bench ecosystem of infrastructure, platform and consulting services from vendors like Joyent Cloud, Nodejitsu and Clock Ltd. for even easier design, development, and production.
  • mdb_v8, DTrace and flame graphs (visual temporal call graphs) on SmartOS for fast root-cause analysis / debugging.

Nodestack Conference

At the Oct 17 online conference, you’ll talk with:

  • Nodejitsu’s Nuno Job on “Crazy, Cool Things You can do with Node.js”
  • 10gen’s Aaron Heckmann on “Node.js + MongoDB = Love” and why these technologies fit so well together.
  • Joyent’s Bryan Cantrill on “Stack Foundation = SmartOS” on SmartOS’ hypervisor benefits for Nodestack including flexibility for KVM virtualization
  • A panel including 10gen’s Jared Rosoff, Joyent’s Jason Hoffman, Clock Ltd’s Paul Serby and yours truly on the economic benefits of Nodestack.

So please sign up here to join us. The webcast is scheduled to start at 9am PT on Oct 17, 2012.

*If you are local in San Francisco, CA, we’re also inviting a few folks to join us as part of the studio audience. Email ben at mongolab dot com if you’re interested. See our Events page for other events.

Updated: 2012-09-28 with exact start time. Grammar fix ^less^fewer. Added link to Aaron’s preview post; mdb_v8, David Pacheo deck.

2012-10-01 fixed broken SmartOS link.
