The 10 Python Conferences Happening at PyCon 2011 (part 3)

This is the third in a series of posts about the schedule for PyCon 2011. In designing this schedule, we found that there are actually 10 different conferences happening in parallel at PyCon. The first post introduced the series and discussed the Django virtual track. The second post focused on the web working virtual track. This post focuses on the third virtual track, Python and NoSQL.

Python and NoSQL

One of the more interesting developments in the past couple years is the use of NoSQL databases. FOr many years, the default answer to any kind of persistence problem was simply to put it in a (relational) database. If you had problems scaling, then you would shard or pay lots of money for clustered/big iron solutions. NoSQL developed in part as a reaction to the overuse of RDBMSes for all sorts of problems.

Of course, it can be hard to say exactly what NoSQL is - but I like to define it as a resurgence of "the right tool for the job," just applied to the storage and persistence space. It can be graph-based, document-based, column-based, or object based -- or even just a data structures server.

It is not surprising, though, that Python is able to talk to them all. In this track we have four different talks, giving the inside scoop on production-level use of various NoSQL stores.

ZODB: A Python Persistence System by Chris McDonough. The ZODB is the granddaddy of the various NoSQL options for Python, having been developed when such things were "object databases" and not "NoSQL." Nevertheless, the ZODB is a standalone persistence system uniquely integrated into Python that remains astoundingly buzzword-compliant despite its age. This talk will provide a high-level overview of ZODB useful to a novice or intermediate Python programmer. At the end of the talk, an attendee should have a basic understanding of how to create an application which depends on ZODB persistence.

CouchDB and Python in practice by Luke Gotszling. CouchDB has a unique document-centric model with automatic clustering and replication. It is gaining a lot of traction, and has recently been seen both up in the clouds and as a data store on Android phones. This talk will introduce CouchDB and will show how to get it to play well with Python. Luke will continue by showing a python ORM for CouchDB, easing development and object-document interoperability. Finally, Luke will cover parsing CouchDB documents within python, writing view functions in python, map/reduce functions on CouchDB from python, and some lessons learned from managing and distributing a live deployment at scale under high load.

Scaling Python past 100 by Mark Ramm. Those with eagle eyes will spot this as a repeat from the "web working" track. That is because this talk is a twofer - describing both the development of the modern Python codebase as well as the use of MongoDB to address the scaling issues associated with a top 100 site.

MongoDB + Pylons at Catch.com: Scalable Web Apps with Python and NoSQL by Niall O'Higgins. The Catch.com backend provides an API for publishing and querying your personal data - used by many hugely popular Android, iOS and Web clients. Faced with the limits of the initial Catch.com Java/BDB backend implemention, they evaluated various alternative technologies including Amazon SimpleDB, MySQL, Cassandra and MongoDB. They found Python and MongoDB gave them unique flexibility with our data model, allowed them to scale for increased reliability and performance and decreased feature development time - and in this talk they'll describe exactly how.

Edit: Wesley Chun points out that Running Django Apps on Google App Engine is also designed to deal with NoSQL datastores - and that the principles covered in his talk apply both to GAE and to MongoDB. ed.

Is this the conference you want to see? Then, register for PyCon and book your room now! We have picked up a few more rooms - including a few at a lower rate a block away. You can email (pycon4-reg@cteusa.com), or phone (847-759-4277). We have very few spots left.

PyCon 2018 Registration is Now Open!

We’re thrilled to announce the opening of registration for PyCon 2018 in Cleveland, Ohio! The prior six PyCons have sold out, so prepare for another one and get your tickets early. The first 800 tickets sold are priced at an early bird discount, saving over 20% on corporate tickets and over 12% on individual tickets. Students save $25 if they purchase early!

To get started, create an account and head to https://us.pycon.org/2018/registration/ to get your tickets!

You get a package that is hard to beat when you register for PyCon. The conference itself is three days worth of our community’s 95 best talks, amazing keynote speakers each morning, and our famed lightning talks to close out each day, but it’s much more than that. It’s having over 3,000 people in one place to learn from and share with. It’s joining a conversation in the hallway with the creators of open source projects. It’s taking yourself from beginner to intermediate, or intermediate to advanced. For some, it’s getting st…

PyCon Opens Financial Aid Applications

Even though PyCon prides itself on being an affordable conference, registration is one of several expenses an attendee must incur, and it’s likely the smallest one. Flying, whether halfway around the world or from a few hundred miles away, is more expensive. Staying in a hotel for a few days is also more expensive. All together, the cost of attending a conference can become prohibitively expensive. That’s where our Financial Aid program comes in. We’re opening applications for Financial Aid today, and we’ll be accepting them through February 15, 2018.
Once you have an account on the site, you can apply here or through your dashboard.
We offer need-based grants to enable people from across our community to attend PyCon. The criteria for evaluating requests takes into account several things, such as whether the applicant is a student, unemployed, or underemployed; their geographic location; and their involvement in both the conference and the greater Python community. Those presenting at …

Introducing the PyCon Hatchery Program

PyCon is known around the world as the Python community’s premier event, attracting people from 39 countries. Outside of the main track of talks, PyCon is home to a growing number of additional events such as Young Coders, the Education Summit, Language Summit, Poster Session, among others. The conference strives to be globally representative by promoting diversity and inclusion through these additional events and outreach programs.
Our community works to meet these goals year on year. In the past, we have received requests to add events to PyCon but have not had the resources to make them work. Although we are still limited on staff resources, we are proposing a stepping point that may lead us in the right direction. What is the end goal?We want to support our community and enable them to add events to PyCon that are important to our community. The long-term goals of this program are to support and grow sustainable events that will become a recurring part of PyCon itself or find a home…
