AI-native multimodal data warehouse with Snowflake-compatible SQL
Open-source cloud data warehouse built in Rust. Analyze structured, semi-structured, vector, and geospatial data with unified SQL. Deploy locally, self-host, or use managed cloud.
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.
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.
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.
When teams consider Databend, these hosted platforms usually appear on the same shortlist.
Looking for a hosted option? These are the services engineering teams benchmark against before choosing open source.
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
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.
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.
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.
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.
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.
