StarRocks is a query engine for sub-second, ad-hoc analytics both on and off the data lakehouse. It eliminates the need for denormalization and adapts to your use cases, without having to move your data or rewrite SQL.
This is free and open source software.
Features include:
- Native vectorized SQL engine: It adopts vectorization technology to make full use of the parallel computing power of CPU, achieving sub-second query returns in multi-dimensional analyses, which is 5 to 10 times faster than previous systems.
- Standard SQL: StarRocks supports ANSI SQL syntax (fully supported TPC-H and TPC-DS). It is also compatible with the MySQL protocol. Various clients and BI software can be used.
- Smart query optimization: The software can optimize complex queries through CBO (Cost Based Optimizer). With a better execution plan, the data analysis efficiency will be greatly improved.
- Real-time update: The updated model of the database can perform upsert/delete operations according to the primary key, and achieve efficient query while concurrent updates.
- Intelligent materialized view: The materialized view of StarRocks can be automatically updated during the data import and automatically selected when the query is executed.
- Querying data in data lakes directly: It allows direct access to data from Apache Hive, Apache Iceberg, Delta Lake and Apache Hudi without importing.
- Resource management: This feature allows the program to limit resource consumption for queries and implement isolation and efficient use of resources among tenants in the same cluster.
- Easy to maintain: Simple architecture makes it easy to deploy, maintain and scale out. StarRocks tunes its query plan agilely, balances the resources when the cluster is scaled in or out, and recovers the data replica under node failure automatically.
