It supports the standard SQL and is compatible with the MySQL protocol. You can use the standard SQL to perform data analysis, without the need to understand the data structure of different data infrastructures or learn new programming languages.

High Concurrent Query

With proper architecture design and flexible resource allocation policies, it supports tens of thousands to hundreds of thousands of concurrent queries per second, enabling thousands of users to perform data analysis concurrently.

Excellent Performance

The new vectorization execution engine and strong MPP execution framework are used, and the star schema and snowflake schema are supported, to provide subsecond query result response for analysis with PB-level data volume.

Elastic Scaling

It takes simple operations on the console to quickly scale out and scale in the clusters and modify the CPU and memory configurations in the node, to quickly and stably support business development and reduce cost waste.

Safe and Reliable

Redundancy based on dual-node data synchronization realizes seamless failover and redundant backup.
