Serban Teodorescu of Adobe presents “Cassandra in Adobe Audience Manager” on various topics covering what Adobe has done in more or less different ways than most.
About the Presenter
Serban is an SRE at Adobe, where he’s part of a small team that manages 30+ Cassandra clusters for Adobe Audience Manager. Previously, he was a Python programmer, and he’s still trying to find out how a developer who preferred SQL databases ended up as an SRE for a Cassandra team. Apart from Cassandra and Python, he’s interested in automating his tasks with terraform, AWX, and StackStorm.
Apache Cassandra is an open source NoSQL distributed database trusted by thousands of companies for scalability and high availability without compromising performance. Linear scalability and proven fault-tolerance on commodity hardware or cloud infrastructure make it the perfect platform for mission-critical data.
