Explore the fundamental concepts of Apache Pinot™ as a distributed OLAP database.

Concepts

Apache Pinot™ is a database designed to deliver highly concurrent, ultra-low-latency queries on large datasets through a set of common data model abstractions. Delivering on these goals requires several foundational architectural commitments, including:

• Storing data in columnar form to support high-performance scanning
• Sharding of data to scale both storage and computation
• A distributed architecture designed to scale capacity linearly
• A tabular data model read by SQL queries

To learn about Pinot components, terminology, and gain a conceptual understanding of how data is stored in Pinot, review the following sections:
