I have been working in core database internals for 35 years and at Oracle for 12 years. I have worked on the implementations of tables scans, Hybrid Columnar Compression, Exadata Offload, Big Data SQL, and I am part of the In-Memory team. My current role is Software Architect for Exadata (and Big Data SQL) Smart Scan. Before Oracle I was the architect for Sybase IQ Query Engine - the world’s first commercial columnar database and was the first chairman of the TPC-H subcommittee.
