## What it is
Dremio is an open-source data lakehouse platform that lets users query and analyze data across data lakes, object storage, and databases with SQL, without moving or copying data. It provides a web UI, connectors to BI tools like Tableau and Power BI, and high-performance query acceleration.

## Use cases
- query data lakes with sql
- self-hosted lakehouse analytics engine
- connect tableau and power bi to s3 data
- accelerate bi dashboards without extracts
- federated queries across snowflake redshift and data lakes
- sql analytics for data science notebooks

## When to choose
- you need fast SQL analytics directly over data lake or object storage files
- you want one semantic layer serving multiple BI tools without data copies
- you need a self-hosted or cloud lakehouse with Apache Arrow Flight connectivity

## When to avoid
- you only need a lightweight embedded database or simple OLTP store
- your team lacks capacity to operate a JVM-based distributed data platform
- you need a small single-node tool rather than a full analytics platform
