Deployment prerequisites

This topic describes the hardware and software requirements that your servers must meet before deploying StarRocks. For recommended hardware specifications of your StarRocks cluster, see Plan your StarRocks cluster.

Hardware​

CPU​

StarRocks relies on AVX2 instruction sets to fully unleash its vectorization capability. Therefore, in a production environment, we highly recommend you deploy StarRocks on machines with x86 architecture CPUs.

You can run the following command in your terminal to check if the CPUs on your machines support the AVX2 instruction sets:

cat /proc/cpuinfo | grep avx2

NOTE

ARM architecture does not support SIMD instruction sets, and therefore is less competitive than x86 architecture in some scenarios. Therefore, we only recommend deploying StarRocks on ARM architecture in a development environment.

Memory​

No specific requirement is imposed on memory kits used for StarRocks. See Plan StarRocks cluster - CPU and Memory for the recommended memory size.

Storage​

StarRocks supports both HDD and SSD as storage medium.

If your applications require real-time data analytics, intensive data scans, or random disk access, we strongly recommend you use SSD storage.

If your applications involve Primary Key tables with the persistent index, you must use SSD storage.

Network​

We recommend that you use 10 Gigabit Ethernet networking to ensure stable data transmission across nodes within your StarRocks cluster.

Operating system​

StarRocks supports deployments on CentOS Linux 7.9 or Ubuntu Linux 22.04.

Software​

You must install JDK 8 on your servers to run StarRocks. For v2.5 and later versions, JDK 11 is recommended.

CAUTION

  • StarRocks does not support JRE.
  • If you want to install StarRocks on Ubuntu 22.04, you must install JDK 11.

Follow these steps to install JDK 8:

  1. Navigate to the path for the JDK installation.

  2. Download JDK by running the following command:

    wget --no-check-certificate --no-cookies \
        --header "Cookie: oraclelicense=accept-securebackup-cookie"  \
        http://download.oracle.com/otn-pub/java/jdk/8u131-b11/d54c1d3a095b4ff2b6607d096fa80163/jdk-8u131-linux-x64.tar.gz
