Why Build a Data Lakehouse?

Unified Access

Eliminate data silos. Query your data where it lives—in S3, ADLS, or GCS—without moving it.

Open Standards

Avoid vendor lock-in. Use open formats like Apache Iceberg and open catalogs to keep your data accessible to any engine.

High Performance

Achieve sub-second query performance on data lake scale datasets using engines like Dremio.
