Databend Serverless Cloud (beta) | Documentation | Benchmarking | Roadmap (v1.1)

Databend is an open-source Elastic and Workload-Aware modern cloud data warehouse focusing on Low-Cost and Low-Complexity for your massive-scale analytics needs.

Databend uses the latest techniques in vectorized query processing to allow you to do blazing-fast data analytics on object storage: (S3, Azure Blob, Google Cloud Storage, Alibaba Cloud OSS, Tencent Cloud COS, Huawei Cloud OBS, Cloudflare R2, Wasabi or MinIO).

• Feature-Rich

  Support for atomic operations including SELECT/INSERT/DELETE/UPDATE/REPLACE/COPY/ALTER and advanced features like Time Travel, Multi Catalog(Apache Hive/Apache Iceberg).

• Instant Elasticity

  Databend completely separates storage from compute, which allows you easily scale up or scale down based on your application's needs.

• Blazing Performance

  Databend leverages data-level parallelism(Vectorized Query Execution) and instruction-level parallelism(SIMD) technology, offering blazing performance data analytics.

• Git-like MVCC Storage

  Databend stores data with snapshots, enabling users to effortlessly query, clone, or restore data from any history timepoint.

• Support for Semi-Structured Data

  Databend supports ingestion of semi-structured data in various formats like CSV, JSON, and Parquet, which are located in the cloud or your local file system; Databend also supports semi-structured data types: ARRAY, TUPLE, MAP, JSON, which is easy to import and operate on semi-structured.

• MySQL/ClickHouse Compatible

  Databend is ANSI SQL compliant and MySQL/ClickHouse wire protocol compatible, making it easy to connect with existing tools(MySQL Client, ClickHouse HTTP Handler, Vector, DBeaver, Jupyter, JDBC, etc.).

• Easy to Use

  Databend has no indexes to build, no manual tuning required, no manual figuring out partitions or shard data, it’s all done for you as data is loaded into the table.
