Management
๐๏ธ logs
When deploying and operating StarRocks, understanding and properly using the logging system is critical for troubleshooting, performance analysis, and system tuning. This article provides a detailed overview of the log file types, typical content, configuration methods, and log rolling and retention strategies for both the Frontend (FE) and Backend (BE or CN) components of StarRocks.
๐๏ธ Process Profile (Proc Profile)
The Process Profile (Proc Profile) feature provides a built-in mechanism to collect and visualize performance profiles for StarRocks Frontend (FE) and Backend (BE) processes. By generating flame graphs for CPU and memory allocation, it helps developers and administrators diagnose performance bottlenecks, high resource utilization, and complex runtime issues directly from the Web UI.
๐๏ธ Scale in and out
This topic describes how to scale in and out the node of StarRocks.
๐๏ธ Manage BE and CN Blacklist
From v3.3.0 onwards, StarRocks supports the BE Blacklist feature, which allows you to forbid the usage of certain BE nodes in query execution, thereby avoiding frequent query failures or other unexpected behaviors caused by the failed connections to the BE nodes. A network issue preventing connections to one or more BEs would be an example of when to use the blacklist.

๐๏ธ Graceful Exit
From v3.3 onwards, StarRocks supports Graceful Exit.
๐๏ธ Develop Static Extensions
Static Extensions are StarRocks FEโs extension modules that allow you to add new features or optimize existing functionality without modifying the core code. Compared to dynamic plugins, static extensions are automatically loaded at system startup and provide more registrable extension points, covering the systemโs core modules.
