Concepts

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

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
