The Query Processing sub-team (QP) owns everything in the life cycle of a SQL statement like Parsing, Analysis (syntax and semantic), Rewriting, Planning (Optimizer) and Execution while providing customers access to observability metrics to help them understand their database performance better. As an Engineer on this team, you will be responsible for building a highly distributed and performant database system with a focus on query processing. This will involve designing and implementing key query processing components such as the query optimizer, planner, and execution engine. You will work on optimizing queries through techniques like heuristic-based rewrites, cost-based optimizations, improved cardinality estimations, and leveraging runtime feedback to enhance the query optimization process. You will be identifying and resolving performance bottlenecks in the overall query processing system to ensure efficient and scalable database operations.
