Hardware requirements

This topic describes hardware requirements and recommendations for production deployments. Actual resource requirements may vary based on your specific workload.

Supported architectures​

RisingWave can run on the following hardware architectures:

  • x86_64 (64-bit Intel/AMD CPUs)
  • ARM64
  • Mac with Apple Silicon

Compute nodes​

Compute nodes handle query processing and state management. More resources enable higher query throughput. For cost efficiency, machines with high memory-to-CPU ratios (4:1 or higher) are recommended due to RisingWave's memory-intensive nature.

  • Minimum:
    • 2 CPU cores
    • 8 GB memory
  • Recommended:
    • ≥4 CPU cores
    • ≥16 GB memory

Compactor nodes​

Compactor nodes perform background compaction jobs to optimize state storage. Insufficient resources for compactors will result in slow state access and impact overall performance.

  • Minimum:
    • 1 CPU core
    • 1 GB memory
  • Recommended:
    • ≥2 CPU cores
    • ≥2 GB memory

Meta nodes​

Meta nodes manage metadata and coordinate the cluster. It is advisable to deploy 2 meta nodes (primary and backup) to ensure faster recovery and avoid single points of failure (SPOF).

  • Minimum:
    • 1 CPU core
    • 1 GB memory
  • Recommended:
    • ≥2 CPU cores
    • ≥4 GB memory

Storage​

RisingWave offers support for multiple storage systems as storage backends. For the complete list of supported storage systems for Kubernetes deployments, see Set up a RisingWave cluster in Kubernetes.

Please notice that storage performance can significantly impact RisingWave's performance. We recommend using high-performance cloud storage systems such as AWS S3. For self-managed storage systems such as MinIO or local file system, please ensure to use high-performance SSD disks.
