Hardware and Software Environment Check
This document provides a hardware and software environment reference for deploying Doris.
Hardware environment check
| Check item | Minimum configuration | Recommended configuration |
|---|---|---|
| CPU | Supports the AVX2 instruction set | Supports the AVX2 instruction set |
| Memory | CPU cores x 4 GB | CPU cores x 8 GB |
| Storage | SSD or HDD | SSD |
| File system | ext4 or xfs | ext4 or xfs |
| Network card | 1GbE | 10GbE + link aggregation |
CPU check
Doris uses AVX2 vectorization to accelerate queries. A machine that supports the AVX2 instruction set is recommended.
cat /proc/cpuinfo | grep avx2
If there is output, AVX2 is supported. If it is not supported, you can use the no-AVX2 Doris installation package.
Memory check
Doris does not enforce a memory limit. The following is recommended for production environments:
| Component | Minimum memory | Recommended memory |
|---|---|---|
| FE | 16 GB | 64 GB+ |
| BE | CPU cores x 4 GB | CPU cores x 8 GB |
Storage check
| Scenario | Recommended storage type |
|---|---|
| High-concurrency point queries on large-scale data | SSD |
| High-frequency updates on large-scale data | SSD |
| Cold data archiving | HDD / object storage |
File system check
| File system | Applicable scenario |
|---|---|
| ext4 | General-purpose, good stability |
| xfs | Large-scale data, high-concurrency writes |
Network card check
A 10GbE or faster network is recommended. For machines with multiple network cards, use link aggregation to improve bandwidth and redundancy.
Recommended server configuration
Both x86-64 and ARM64 architectures are supported.
Development and test environments
FE and BE can be deployed together:
- Deploy 1 FE + 1 BE on a single server (multiple instances are not recommended)
- For 3 replicas of data: deploy 1 BE on each of at least 3 servers
| Module | Minimum CPU | Minimum memory | Minimum disk | Network | Instances |
|---|---|---|---|---|---|
| Frontend | 8 cores | 8 GB | SSD/SATA, 10 GB+ | 1GbE/10GbE | 1 |
| Backend | 8 cores | 16 GB | SSD/SATA, 50 GB+ | 1GbE/10GbE | 1 |
Production environment
It is recommended to deploy FE and BE separately. When resources are tight and they must be co-located, place their data on different disks.
| Module | Recommended CPU | Recommended memory | Recommended disk | Network | Instances |
|---|---|---|---|---|---|
| Frontend | 16 cores+ | 64 GB+ | SSD, 100 GB+ | 10GbE | 1 |
| Backend | 16 cores+ | 64 GB+ | SSD/SATA, 100 GB+ | 10GbE | 3 |
Disk space calculation
| Component | Recommended space | Description |
|---|---|---|
| FE | 100 GB+ | SSD, used for metadata storage |
| BE | Total data volume x 3 x 1.4 | LZ4 compression ratio 0.3-0.5, 3 replicas + 40% reserved space for background compaction |
The BE storage calculation above is mainly for the integrated storage and compute deployment mode. In the separated storage and compute deployment mode, all data is stored in shared storage, and the local disk is used only for caching, so the disk size depends on the size of the hot data.
Java environment check
All Doris processes depend on Java.
| Doris version | Java version | Recommended version |
|---|---|---|
| 2.1 (inclusive) and earlier | Java 8 | jdk-8u352+ |
| 3.0 (inclusive) and later | Java 17 | jdk-17.0.10+ |
