Resource request and limits

Resource request and limits can be set for base components and assemblies in KX Insights.

Resource requests and limits for assemblies are set by a k8sPolicy.

Resource requests and limits for base components are set in the install configuration.

numbers

The numbers for limits used on this page are not suggestions, and are meant to demonstrate how to use these settings, not recommend values.

Defaults

The default values for components related to the query path are:

component	cpu requests	cpu limits	memory requests	memory limits
resource-coordinator	100m	1000m	128Mi	256Mi
aggregator	500m	2000m	1024Mi	2048Mi
sg-gateway	250m	1000m	512Mi	4096Mi
dap	100m	100m	128Mi	128Mi
sm	1000m	1000m	4000Mi	4000Mi

Resource limits for base components

To set resource limits for the resource-coordinator, aggregators, and service gateway, set resources in your install configuration.

service-gateway:
  aggregator:
    resources:
      requests:
        memory: "64Mi"
        cpu: "250m"
      limits:
        memory: "128Mi"
        cpu: "500m"
  sg-gateway:
    resources:
      requests:
        memory: "64Mi"
        cpu: "250m"
      limits:
        memory: "128Mi"
        cpu: "500m"
  resource-coordinator:
    resources:
      requests:
        memory: "64Mi"
        cpu: "250m"
      limits:
        memory: "128Mi"
        cpu: "500m"

Resource limits for storage manager and data access processes

To set requests and limits for your databases set a k8sPolicy for the SM and DAP elements of your assemblies.

spec:
  elements:
    sm:
     resourceAllocation: 5
     eoi:
       resourceAllocation: 45
     eod:
       resourceAllocation: 45
     dbm:
       resourceAllocation: 5
     k8sPolicy:
       resources:
         requests:
           memory: "64Mi"
           cpu: "250m"
         limits:
           memory: "128Mi"
           cpu: "500m"
    dap:
      instances:
        hdb:
          k8sPolicy:
            resources:
              requests:
                memory: "64Mi"
                cpu: "250m"
              limits:
                memory: "128Mi"
                cpu: "500m"

Sandbox resource limits and requests

By default, when you query with the UI, the newly created sandboxes get resource limits that match the resource limits of those from the assemblies.

This means that if you set a k8sPolicy for an HDB, the sandbox-hdb will also get those same limits.
