Introduction

📄️ What is StarRocks?

StarRocks is a next-generation, blazing-fast massively parallel processing (MPP) database designed to make real-time analytics easy for enterprises. It is built to power sub-second queries at scale.

📄️ Architecture

StarRocks has a simple architecture. The entire system consists of only two types of components; frontends and backends. The frontend nodes are called FEs. There are two types of backend nodes, BEs, and CNs (Compute Nodes). BEs are deployed when local storage for data is used, and CNs are deployed when data is stored on object storage or HDFS. StarRocks does not rely on any external components, simplifying deployment and maintenance. Nodes can be horizontally scaled without service downtime. In addition, StarRocks has a replica mechanism for metadata and service data, which increases data reliability and efficiently prevents single points of failure (SPOFs).
