The 10 Best Data Warehouses for Machine Learning in 2027

Machine learning runs on data, and for most organizations that data lives in a cloud data warehouse or lakehouse. The right platform does more than store tables: it scales to large training datasets, serves features with low latency, supports SQL and Python side by side, and increasingly runs ML and vector workloads in place so you do not have to export everything.

This ranking covers the ten data warehouse and lakehouse platforms ML teams most rely on in 2027, judged on how well they support the full path from raw data to trained, served models.

Direct Answer

Databricks is the best overall because its lakehouse unifies data engineering, warehousing, and ML — including feature engineering, training, MLflow tracking, and serving — on open formats, so the whole pipeline lives in one governed place. Google BigQuery is the best value because its serverless model means you pay only for queries and storage with no clusters to manage, and BigQuery ML lets you train and run models with plain SQL.

Your choice depends on whether you want a unified ML lakehouse (Databricks), serverless simplicity (BigQuery), elastic separation of compute and storage (Snowflake), or an open lakehouse you assemble yourself (lakehouse formats on object storage).

How We Ranked These

We evaluated each platform on five criteria: scale and performance (handling large training datasets and concurrent jobs), ML integration (native training, feature serving, Python/SQL support, vector search), openness (open table formats and avoiding lock-in), governance (lineage, access control, and cataloging across data and models), and cost model (predictability and efficiency).

Because ML workloads mix big batch reads with feature serving, we weight ML integration and scale most heavily.

1. Databricks 🏆 BEST OVERALL

Databricks pioneered the lakehouse, combining a data warehouse's reliability with a data lake's openness on the Delta Lake format. For ML it is unusually complete: Spark for large-scale processing, notebooks and Python, a feature store, MLflow for tracking and registry, and model serving — all under Unity Catalog governance.

That end-to-end coverage is why so many ML teams standardize on it.

What it is: open lakehouse platform unifying data engineering and ML. Strengths: end-to-end ML (feature store, MLflow, serving), open Delta format, strong governance, Spark scale. Best for: teams wanting one governed platform for data and ML. Pricing/availability: consumption-based on AWS, Azure, and Google Cloud.

2. Google BigQuery 💎 BEST VALUE

BigQuery is Google Cloud's serverless data warehouse. There are no clusters to size — you pay for storage and the queries you run — which keeps both cost and operations low. BigQuery ML lets analysts train and run models, including some deep models and remote LLM calls, directly in SQL, and it integrates with Vertex AI for heavier workflows.

What it is: serverless cloud data warehouse with in-SQL ML. Strengths: zero infrastructure, BigQuery ML in SQL, strong scaling, Vertex AI integration. Best for: teams wanting low-ops analytics plus accessible ML. Pricing/availability: pay-per-query/storage or capacity slots on Google Cloud.

3. Snowflake

Snowflake popularized the separation of compute and storage, letting you spin independent warehouses up and down per workload. For ML, Snowpark runs Python, and Snowflake now offers model and feature capabilities plus Cortex for LLM and vector functions, so teams can do more ML without leaving the platform.

What it is: cloud data platform with elastic compute/storage separation. Strengths: elastic scaling, Snowpark for Python ML, Cortex AI/vector functions, strong sharing and governance. Best for: teams wanting flexible, isolated compute and growing native ML. Pricing/availability: consumption-based across major clouds.

4. Amazon Redshift

Redshift is AWS's data warehouse, tightly integrated with the AWS analytics and ML ecosystem. Redshift ML lets you create and use models via SQL backed by SageMaker, and Redshift connects cleanly to S3, Glue, and SageMaker for end-to-end pipelines on AWS.

What it is: AWS's managed data warehouse. Strengths: deep AWS integration, Redshift ML with SageMaker, mature ecosystem. Best for: AWS-centric teams wanting warehouse-driven ML. Pricing/availability: provisioned or serverless on AWS.

5. Apache Iceberg Lakehouse (on object storage)

Apache Iceberg is an open table format that brings warehouse-grade reliability — schema evolution, time travel, ACID — to data lakes on S3, GCS, or ADLS, queried by engines like Spark, Trino, Snowflake, and BigQuery. Building on Iceberg gives ML teams an open, engine-agnostic foundation that avoids lock-in.

What it is: open table format for lakehouse architectures. Strengths: open and engine-neutral, ACID and time travel, multi-engine access. Best for: teams wanting an open lakehouse they control. Pricing/availability: open source; you pay for storage and query engines.

6. Azure Synapse / Microsoft Fabric

Microsoft Fabric (with Synapse capabilities) is Microsoft's unified analytics platform built around OneLake, integrating warehousing, data engineering, and ML, and connecting directly to Azure Machine Learning. For Microsoft-centric organizations it consolidates analytics and ML in one governed environment.

What it is: Microsoft's unified analytics and lakehouse platform. Strengths: OneLake unification, Azure ML integration, Power BI and Microsoft ecosystem. Best for: Microsoft/Azure organizations. Pricing/availability: capacity-based on Azure.

7. Databricks SQL / Delta Lake (open format)

Beyond the full platform, Delta Lake as an open format is widely used on its own to add reliability and performance to lakes feeding ML. Teams use Delta with various engines to get ACID transactions and efficient reads on training data while keeping data open and portable.

What it is: open lakehouse storage format. Strengths: ACID, performance optimizations, broad engine support, open. Best for: teams wanting reliable open storage under ML pipelines. Pricing/availability: open source; storage and compute costs apply.

8. ClickHouse

ClickHouse is a high-performance columnar database known for extremely fast analytical queries, increasingly used for real-time feature computation and ML analytics where low-latency aggregation over large event data matters. It is available open source and as ClickHouse Cloud.

What it is: fast open-source columnar OLAP database. Strengths: very fast queries, real-time analytics, efficient on large event data. Best for: real-time features and high-speed ML analytics. Pricing/availability: open source or ClickHouse Cloud.

9. Trino / Starburst

Trino is a distributed SQL query engine that queries data where it lives — across warehouses, lakes, and databases — without copying it. Starburst is the enterprise platform around Trino. For ML teams with data scattered across systems, this federated access simplifies building training datasets.

What it is: federated distributed SQL query engine. Strengths: queries many sources without ETL, open, good for assembling datasets. Best for: teams with data spread across multiple stores. Pricing/availability: open source (Trino) or Starburst Galaxy/Enterprise.

10. Teradata VantageCloud

Teradata remains a strong choice for large enterprises with massive, complex analytical workloads. VantageCloud adds in-database analytics and ML functions, letting organizations with heavy existing Teradata investments run ML close to their data at scale.

What it is: enterprise-scale analytics platform with in-database ML. Strengths: proven at very large scale, in-database analytics, enterprise governance. Best for: large enterprises with existing Teradata estates. Pricing/availability: subscription/consumption on major clouds.

Choosing the Right Platform

Start from where your data and cloud already are — BigQuery on Google Cloud, Redshift on AWS, Fabric on Azure — because gravity and integration matter more than benchmarks. If ML is central and you want one governed home for features, training, tracking, and serving, Databricks leads.

If you want minimum operations, BigQuery's serverless model and in-SQL ML are hard to beat. If avoiding lock-in is a priority, build on open formats like Iceberg or Delta and pick engines freely. And for real-time features, pair a warehouse with a fast store like ClickHouse.

Most mature stacks combine a primary warehouse/lakehouse with a feature store and a vector database for retrieval.

Frequently Asked Questions

What's the difference between a data warehouse and a lakehouse for ML? A traditional warehouse stores structured, modeled data optimized for SQL analytics. A lakehouse (Databricks, or Iceberg/Delta on object storage) adds warehouse reliability — ACID, schema management, time travel — directly on open files in a data lake, so you can serve both BI and ML, including unstructured data, from one governed copy without heavy ETL between systems.

Can I train models directly in the warehouse? Often yes for many model types. BigQuery ML, Redshift ML, and Snowflake (via Snowpark and Cortex) let you train and run models using SQL or Python in the platform. This is great for accessibility and avoiding data movement, though heavy deep-learning training usually still runs on dedicated GPU infrastructure, with the warehouse feeding the data.

Do I still need a feature store if I have a warehouse? For complex ML, usually yes. A warehouse stores data; a feature store adds consistent feature definitions, point-in-time-correct training data, and low-latency online serving so training and inference use identical features.

Databricks and some platforms now include feature-store capabilities, blurring the line, but the function is distinct.

How do these platforms handle vector search for RAG? Several now offer it natively: Snowflake Cortex, BigQuery, and others provide vector functions and embeddings, and Databricks offers vector search. For large or latency-critical RAG you may still use a dedicated vector database, but keeping vectors next to your governed data simplifies pipelines for many use cases.

Which is most cost-predictable? It depends on workload shape. Serverless BigQuery is predictable for bursty query patterns since you pay per query/storage. Snowflake and Databricks consumption scales with compute you provision, which is efficient if you manage warehouse sizing and auto-suspend.

Open lakehouse on object storage minimizes storage cost but shifts engine costs to you.

How do I avoid vendor lock-in? Standardize on open table formats — Apache Iceberg or Delta Lake — stored in your own object storage, and use engines that read them (Spark, Trino, Snowflake, BigQuery). That keeps your data portable across query engines and clouds, so you can change platforms without a painful data migration.
