Learn how partition design can be used to improve query performance in the context of Apache Iceberg and Dremio Reflections. We will start with an overview of Dremio Reflections and how partition design plays a key role in query planning…

Dremio maintains physically optimized representations of source data known as Data Reflections. It can be thought of as a hybrid between materialized views and indexes. This way, Dremio’s query optimizer can accelerate a query by utilizing one or more reflections to partially or entirely satisfy a query, rather than processing the raw data in the […]
