Overview

Modern Data Warehouse for the AI Era

Databend is a multimodal cloud data warehouse designed for organizations seeking Snowflake compatibility without vendor lock-in. Built in Rust with vectorized execution and S3-native storage, it delivers enterprise-grade analytics across structured, semi-structured, vector, and geospatial data through a unified SQL interface.

Built-In AI Capabilities

Unlike traditional warehouses requiring separate systems, Databend integrates vector search, AI functions, embedding generation, and full-text search natively. Query Parquet, CSV, NDJSON, Avro, and ORC files directly from object storage while maintaining production-proven performance at petabyte scale—trusted by enterprises processing 100+ million queries daily across 800+ petabytes.

Flexible Deployment

Install locally with pip install databend for development, self-host with Docker, or provision managed cloud clusters. All deployment modes share the same data seamlessly through S3-compatible storage. Enterprise features include fine-grained access control, data masking, and comprehensive audit logging. Licensed under Apache 2.0 and Elastic 2.0, Databend offers complete data sovereignty while claiming 10x faster performance and 90% cost reduction compared to proprietary alternatives.

Highlights

Snowflake-compatible SQL with multimodal data support (structured, vector, geospatial)
Native AI functions: vector search, embeddings, and full-text search built-in
S3-native architecture with Rust-powered vectorized execution engine
Unified deployment: local Python install, Docker self-host, or managed cloud

Pros

  • Proven at petabyte scale with 800+ PB production deployments
  • No vendor lock-in with S3-compatible storage and Apache/Elastic licensing
  • Single system for analytics and AI workloads eliminates infrastructure complexity
  • Seamless data sharing across local, self-hosted, and cloud environments

Considerations

  • Dual licensing (Apache 2.0 + Elastic 2.0) may restrict certain commercial use cases
  • Smaller ecosystem and community compared to established data warehouses
  • Performance claims (10x faster, 90% cost reduction) require validation for specific workloads
  • Rust codebase may present steeper learning curve for contributors

Fit guide

Great for

  • Organizations seeking Snowflake alternatives with lower infrastructure costs
  • AI/ML teams requiring integrated vector search and embedding capabilities
  • Data engineers needing flexible deployment across local, cloud, and hybrid environments
  • Enterprises analyzing petabyte-scale data with strict data sovereignty requirements

Not ideal when

  • Teams requiring mature third-party integrations and extensive vendor ecosystem
  • Organizations with strict requirements for single-license open-source software
  • Projects needing extensive GUI-based administration tools
  • Use cases demanding real-time streaming ingestion as primary workload

How teams use it

Snowflake Migration with Cost Optimization

Maintain SQL compatibility while reducing cloud warehouse costs by up to 90% through S3-native storage and eliminating proprietary compute overhead

Unified AI/Analytics Platform

Consolidate vector databases and data warehouses into single system, running semantic search and traditional BI queries with unified SQL interface

Data Lake Analytics

Query Parquet, Avro, ORC, and CSV files directly from S3 without ETL, enabling ad-hoc analysis on petabyte-scale data lakes

Hybrid Development Workflow

Develop and test locally with pip-installed Databend, then deploy to production cloud clusters while accessing the same S3-backed warehouse data

Frequently asked questions

How does Databend compare to Snowflake?

Databend provides Snowflake-compatible SQL and similar warehouse capabilities but runs on your S3 storage, eliminating vendor lock-in. It adds native AI functions like vector search and claims significant cost reductions through Rust-based execution and open-source architecture.

Can I run Databend locally for development?

Yes. Install with `pip install databend` for Python-based local development, or use Docker. Local instances can connect to the same S3 data as production cloud clusters, enabling seamless development workflows.

What data formats and sources does Databend support?

Databend handles structured tables, semi-structured JSON, vector embeddings, and geospatial data. It queries Parquet, CSV, TSV, NDJSON, Avro, and ORC files directly from S3-compatible storage without requiring ETL.

What licensing applies to Databend?

Databend uses dual licensing: Apache License 2.0 and Elastic License 2.0. Review the licensing FAQs in the repository to understand restrictions for your specific commercial use case.

Is Databend production-ready?

Yes. Databend is deployed in production environments managing over 800 petabytes of data and processing 100+ million queries daily. It includes enterprise features like access control, data masking, and audit logging.
