What is Databend?

Databend is an open-source Elastic and Workload-Aware modern cloud data warehouse.

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, Huawei Cloud OBS or MinIO).

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 Storage

Databend stores data with snapshots. It's easy to query, clone, and restore historical data in tables.
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, 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 Client, 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.
