Jesus Camacho Rodriguez, Principal Software Engineer, Cloudera
In this talk, Jesus describes the innovations on the journey from batch tool to full-fledged SQL enterprise data warehousing system. In particular, he shows how the community expanded the utility of the system by adding row-level transactional capabilities required for data modifications in star schema databases, introducing optimization techniques that are useful to handle today’s view hierarchies and big data operations, implementing the runtime improvements necessary to bring query latency and concurrency into the realm of interactive operation, and laying the groundwork for using Apache Hive as a relational front end to multiple storage and data systems. All these enhancements were introduced without ever compromising on the original characteristics that made the system popular.
