Apache Pinot is an open-source, real-time distributed database for low-latency, high-throughput queries on large-scale datasets. As industries like e-commerce and IoT demand real-time analytics, Pinot's original single-stage query engine (SSQE) struggled with complex queries involving joins and window functions.

The Multi-Stage Query Engine (MSQE) addresses these challenges, enabling advanced relational operators and supporting complex query execution. In this session, we’ll delve into MSQE’s key innovations, including its integration with Apache Calcite for smart query planning and gRPC for efficient inter-server communication. We’ll also explore strategies for optimizing data shuffling, thread management, and query execution statistics to scale across large environments.

Join us to discover how MSQE extends Pinot’s capabilities, overcomes its limitations, and transforms it into a robust solution for modern data analysis.
