Databend

Databend is an open source, cloud native data warehouse written in Rust and built entirely on object storage. It has grown from an analytics engine into a unified multimodal database that handles business intelligence analytics, AI vector search, full text search and geospatial analysis on one platform, all through Snowflake compatible SQL. It is built for data engineers, analytics teams and developers who want a single engine instead of separate systems for warehousing, vector retrieval and search. Structured, semi structured, unstructured and vector data share the same storage, and embeddings, vector indexes and semantic retrieval run in SQL. Real time ingestion and transformation use Stream and Task, with connectors for Kafka, dbt, Airbyte, Flink CDC, Debezium and others. Client options include BendSQL, drivers for Java, Go, Python, Node.js and Rust, and an MCP server and client. It plugs into tools such as Jupyter, Metabase, Grafana, Superset and Tableau. Databend comes in two forms. Databend Cloud is a fully managed serverless warehouse with a cold start under 500 milliseconds, SOC 2 Type II attestation, and 200 dollars in free credits to start. Databend Enterprise is self hosted on the open source core with enterprise support. Paid rates for either option are not published in the documentation overview.
