Dave Johnson on open web technologies, social software and software development
I've been working at Apigee since September 2013 and one of the things I love most about my new job is the fact that I'm actively contributing to open source again.
I'm working on Apache Usergrid (incubating), an open source Backend-As-A-Service (BaaS) that's built on the Apache Cassandra database system. Apigee uses Usergrid as part of Apigee Edge (see the Build Apps part of the docs).
Apigee contributed code for Usergrid to the Apache Software Foundation back in October 2013 and Usergrid is now part of the Apache Incubator. The project is working towards graduating from the Incubator. That means learning the Apache way, following the processes to get a release out and most importantly, building a diverse community of contributors to build and maintain Usergrid.
One on the most important parts of building an open source community is making it easy for people to contribute and and that's why I submitted a talk to the ApacheCon US 2014 conference (April 7-9 in Denver, CO) titled How to Contribute to Usergrid.
The talk is intended to be a briefing for contributors, one that will lead you through building and running Usergrid locally, understanding the code-base and test infrastructure and how to get your code accepted into the Usergrid project.
Here's the outline I have so far:
I'm in the process of writing this talk now so suggestions and other feedback are most welcome.
Newer versions of Apache Cassandra include CQL, an SQL-like query language that supports both query, update and delete statements as well as the Data Definition Language (DDL) statements like create and alter for tables and indexes. You can create tables (known as column families in Cassandra lingo) just like you can in a relational database, but there are some caveats.[Read More]
