Reference

Since version 3.0, StarRocks supports the AUTOINCREMENT column attribute, which can simplify data management. This topic introduces the application scenarios, usage and features of the AUTOINCREMENT column attribute.

📄️ Generated columns

Since v3.1, StarRocks supports generated columns. Generated columns can be used to accelerate queries with complex expressions. This feature supports precomputing and storing the results of expressions and query rewrites, which significantly accelerates queries with the same complex expressions.

📄️ System variables

StarRocks provides many system variables that can be set and modified to suit your requirements. This section describes the variables supported by StarRocks. You can view the settings of these variables by running the SHOW VARIABLES command on your MySQL client. You can also use the SET command to dynamically set or modify variables. You can make these variables take effect globally on the entire system, only in the current session, or only in a single query statement.

📄️ System limits

📄️ AWS IAM policies

A policy in AWS IAM declares a set of permissions on a specific AWS resource. After creating a policy, you need to attach it to an IAM role or user. As such, the IAM role or user is assigned the permissions declared in the policy to access the specified AWS resource.
