ColumnStore Minimum Hardware Specification

The following table outlines the minimum recommended production server specifications which can be followed for both on premise and cloud deployments:

Per Server

ItemDevelopment EnvironmentProduction Environment
Physical Server8 Core CPU, 32 GB Memory64 Core CPU, 128 GB Memory
StorageLocal diskStorageManager (S3)

Network

Network InterconnectIn a multi server deployment data will be passed around via TCP/IP networking. At least a 1G network is recommended.

Details

These are minimum recommendations and in general the system will perform better with more hardware:

  • More CPU cores and servers will improve query processing response time.
  • More memory will allow the system to cache more data blocks in memory. We have users running system with anywhere from 64G RAM to 512 G RAM for UM and 32 to 64 G RAM for PM.
  • Faster network will allow data to flow faster between UM and PM nodes.
  • SSD's may be used, however the system is optimized towards block streaming which may perform well enough with HDD's for lower cost.
  • Where it is an option, it is recommended to use bare metal servers for additional performance since ColumnStore will fully consume CPU cores and memory.
  • In general it makes more sense to use a higher core count / higher memory server for single server or 2 server combined deployments.
  • In a deployment with multiple UM nodes the system will round robin requests from the mysqld handling the query to any ExeMgr in the cluster for load balancing. A higher bandwidth network such as 10g or 40g will be of benefit for large result set queries.

AWS instance sizes

For AWS our own internal testing generally uses m4.4xlarge instance types as a cost effective middle ground. The R4.8xlarge has also been tested and performs about twice as fast for about twice the price.
