A new meetup for data herders focusing on distributed databases, scaling, and any related data or messaging systems.

The first presentation will be by Michael Schurter on MongoDB - particularly the pros and cons Urban Airship has discovered while running half a dozen MongoDB servers.

Erik Onnen will be giving a 5 minute lightning talk on how he plans to use Kafka at Urban Airship.

Beer and possibly snacks will be provided by Urban Airship.

Please RSVP so we know about how many people to expect.

IMPORTANT: PLEASE RSVP AT THE URL ABOVE, IT'S FREE!

ALSO: The date has changed to Tuesday.

ScaleOutCamp PDX (CloudCamp) is an unconference where early adopters of Cloud Computing technologies exchange ideas. With the rapid change occurring in the industry, we need a place where we can meet to share our experiences, challenges and solutions. At ScaleOutCamp, you are encouraged to share your thoughts in several open discussions, as we strive for the advancement of Cloud Computing. End users, IT professionals and vendors are all encouraged to participate.

10gen: Intro to MongoDB and Schema Design

One of the challenges that comes with moving to MongoDB is figuring how to best model your data. While most developers have internalized the rules of thumb for designing schemas for RDBMSs, these rules don't always apply to MongoDB. The simple fact that documents can represent rich, schema-free data structures means that we have a lot of viable alternatives to the standard, normalized, relational model. Not only that, MongoDB has several unique features, such as atomic updates and indexed array keys, that greatly influence the kinds of schemas that make sense. Understandably, this begets good questions:

• Are foreign keys permissible, or is it better to represent one-to- many relations withing a single document?
• Are join tables necessary, or is there another technique for building out many-to-many relationships?
• What level of denormalization is appropriate?
• How do my data modeling decisions affect the efficiency of updates and queries?

In this session, we'll answer these questions and more, provide a number of data modeling rules of thumb, and discuss the tradeoffs of various data modeling strategies.

ABOUT THE GROUP: The Portland Ruby Brigade is a user group for Ruby programmers in the Portland Oregon area. Join other developers for presentations and discussions about Ruby, libraries, tools and techniques. The group usually meets on the first Tuesday of the month, "Ruby Tuesday".

Get 10% off this developer event with code, "epdx_10"! (That's on top of the 50% early bird special - ends March 18!) The Cloud Foundry Open Tour gives enterprise developers expert instruction on how to get the best results from Platform-as-a-Service in the cloud. Register for this event to learn: * Basic Cloud Foundry commands for both the public and micro clouds *Cloud application development tips for Spring, Java, Ruby and Node.js * How to connect to application services like MySQL, MongoDB, Redis and RabbitMQ

Meet the experts behind the leading open source cloud platform for enterprise applications, discuss the latest innovations with other developers and expand your opportunities by attending the Cloud Foundry Open Tour.

Ahoy everyone! This shindig is going to be the first ever Meetup of the Portland MongoDB User Group. This event is going to be entirely about socializing, getting to know each other, and enjoying some savory spirits! In the future, I like to have a healthy mix of socializing, hands on coding, lectures and anything else you folks throw my way!

COPIOUS is a user-centered digital experience agency. We build digital products with the user at heart and technology in our bones. We recently moved to a new office and now have a large space to host our TechTalks.

About TechTalks:

COPIOUSLabs TechTalks series meets every other Friday at 1pm at the COPIOUS offices. Our talks span artificial intelligence, new programming languages and techniques, computational linguistics, geographic data processing, systems and software architecture, augmented reality, network security, and more as proposed to the Copious engineering team.

About this talk:

Speaker: Andrew Gauger, Systems Engineer, Rejuvenation

MongoDB allows for abstracted data storage, so Andrew will talk about implementations of this flexible data design pattern. State machine and its ability to extend a document asynchronously gets highlighted. We will talk about data abstraction, and how to abstract structured data into a schema-less logger to perform validation.

In this TechTalk, Andrew will aim to describe clustering and replication as well as referencing and embedding in a simple language. The samples come fast but keep to explaining a simple topic. The talk diverges about how distributed database technology can be brought to firmware, how massive quantity small computing instances best leverage this technology, and what frameworks exist to leverage MongoDB on an upcoming project.

All are welcome to attend. If you have a talk that you'd like to suggest presenting, please email it to [email protected] along with a brief outline of what you'd like to cover.

An Evening with MongoDB Portland is a free evening event in Portland, dedicated to the open source, document database MongoDB. An Evening with MongoDB Portland is an opportunity to explore MongoDB and its use cases.

WHAT TO EXPECT:

Walk away with immediately applicable skills Learn new techniques for scaling your infrastructure Network with fellow technologists in your local community and MongoDB engineers

MongoDB Architectural Overview

The Document Data Model

Intelligently Place Data Where You Need It

Freedom to Run Anywhere

Live Atlas demonstration

MongoDB has become one of the fastest growing databases since its inception a little over 10 years ago. In this session, representatives from MongoDB will provide an introduction to the fundamentals of the database, including data storage, data retrieval, and deployment. We will also walk attendees through a demonstration of Atlas, our fully-managed database-as-a-service. Attendees will gain a deeper understanding of where MongoDB shines, and how to get started using MongoDB for their own projects.
