Dremio Arctic

An intelligent metastore for Apache Iceberg that uniquely provides users a Git-like experience for data and automatically optimizes data to ensure high performance analytics.

Automate your lakehouse
and simplify data workflows

  • Automatic data optimization

    Arctic automates all the tedious bits of data management for the lakehouse, including compaction, repartitioning, and indexing, so data teams no longer need to worry about how data is physically organized in files.

  • Isolation and consistency

    Use git-like branching to transform data across tables and schemas in isolation without impacting production workloads, and merge your data changes once they’re tested and ready.

  • Reproduce models and dashboards

    Turn back the clock on your entire lakehouse environment (not just a single table) and reproduce ML models or dashboards based on a specific point in time. Track the evolution of lakehouse data over time, with visibility into who made changes to data.

Key Arctic capabilities

Data optimization

A data optimization service that automates data management tasks in your lakehouse, including compaction, repartitioning, and indexing, so any compute engine running on that data can operate more efficiently.
