Dremio Reflections is a feature of the Dremio data lakehouse platform that automatically creates and maintains optimized data structures, allowing for faster data processing and analytics. Reflections are precomputed summaries of data that are designed for specific analytic queries.
By creating these optimized structures, Dremio Reflections significantly improve query performance, reduce latency, and enable interactive analytics on even the largest datasets. With Reflections, users can experience near-instantaneous query results, enabling them to explore and analyze data with greater speed and efficiency.
Dremio Reflections work by leveraging the metadata and query optimization capabilities of the Dremio platform. When a query is executed, Dremio analyzes the query patterns and data usage to identify which datasets and columns are frequently accessed.
Using this information, Dremio automatically creates and maintains Reflections, which are pre-aggregated and indexed structures that capture the most commonly executed queries and their results. These Reflections are stored separately from the raw data, allowing for efficient data retrieval and query execution.
When a query is submitted to Dremio, the query optimizer identifies if a Reflection can be used to accelerate the query. If a suitable Reflection exists, Dremio will utilize it to provide faster query results, eliminating the need to process the raw data every time.
