Slides: https://www.slideshare.net/DataStax/oracle-let-my-people-go-shu-zhang-ilya-sokolov-symantec-cassandra-summit-2016 | Migration from relational world to no-SQL solutions not only impacts architectures, it requires change in mindset to understand/adjust to no-SQL design. We're going to talk about challenges, both technical and personal (such as resistance to change, endorse collisions, be faster, data model re-design for no-SQL, big data analytics etc.), we ran into during our quest to take major Symantec and Norton products away from the land of transactions. This is how we learned to stop worrying and love the eventual consistency... About the Speakers Ilya Sokolov Technical Director / Architect, Symantec I was working as a software developer and architect in many companies across the world. Being always fascinated with information security I enjoy challenges in identity, digital protection and data storage space helping millions of Symantec customers feel safe online. If I'm not working on a new Norton component or looking for software vulnerabilities at Symantec CyberWar games, you'll likely find me evangelizing new information technology architectures and designs. Shu Zhang Director, Database Engineering, Symantec I started my career as an Oracle PL/SQL programmer and soon became an Oracle DBA. I was an Oracle DBA for over twelve years, including the seven years where I worked in Oracle USA. About three years ago, I became fascinated with the NoSQL world. I have learned MongoDB, Elastic Search, Couchbase and Cassandra. Now I lead a team of fourteen database engineers, responsible for choosing the most appropriate database technology, implementing and supporting all Norton database backend.
