"PuppetDB: New Adventures in Higher-Order Automation" by Deepak Giridharagopal, Director of Engineering, Puppet Labs. Presentation Overview: PuppetDB gives users fast, robust, centralized storage for Puppet-produced data. The 1.0 version landed at Puppetconf 2012, and now we're one year older and one year wiser. It's been deployed in thousands of sites, people have written libraries and tools on top of it, and there's been plenty of activity in the past year. We've tightly integrated it into Puppet Enterprise. We've added new features like report storage, event querying, import/export, better HTTP endpoints, and unified querying. And though we've added features, we've also made PuppetDB faster and consume less disk space. This talk will cover what's happened in the PuppetDB world between Puppetconf 2012 and now. We'll go into the new features, talk about performance and correctness, and discuss lessons learned. Speaker Bio: Deepak is Director of Engineering at Puppet Labs, one of the authors of PuppetDB, and a many-times-over Puppetconf veteran. Prior to joining Puppet Labs, he was Principal Engineer at Dell/MessageOne, using Puppet to manage thousands of production systems.
