One Data Foundation. Every Query Engine.
Zero Re-Platforming.

Power all AI workloads on a single, unified data lakehouse foundation.

MinIO AIStor combines a built-in Iceberg V3 REST Catalog, structured tables in open table formats and S3 object storage in one layer, so every engine reads the same governed data.

Customer Story

Is the Foundation Under Your Lakehouse Ready for AI?

Three ways the storage layer holds lakehouses back, and how AIStor fixes each one.

Fragmented Data

Tables in one system, unstructured data in another, and a separate catalog service to keep in sync. Every copy is one more thing to govern.

The AIStor fix
One governed copy. Tables and objects in one namespace, with the Iceberg V3 REST Catalog built in.

Rising Costs

Appliance renewals, egress and per-operation fees grow faster than the data, so the budget is hard to forecast.

The AIStor fix
40% lower TCO than appliance-based alternatives, on commodity servers. Capacity-based licensing, no egress or per-operation fees.

Legacy Hadoop

NameNodes, DataNodes and constant rebalancing, while the skills to run HDFS disappear from the market.

The AIStor fix
S3-compatible object storage on the hardware you already own, with a 60% smaller footprint.
How it works

MinIO AIStor Builds the Catalog Into the Storage

Most lakehouses run object storage, a table format and a separate catalog service that has to be deployed, secured and kept in sync. With the Apache Iceberg V3 REST Catalog built directly into the store, your engines read one governed copy with one less system in between.

AI/ML within a Data Lakehouse Architecture

Traditional, generative and agentic AI each need different things from your data infrastructure, but they don't need separate stacks. RAG vs. fine-tuning, MLOps and GPU throughput.
