Package org.linuxforhealth.fhir.operation.bench

Class BenchOperation

java.lang.Object

org.linuxforhealth.fhir.server.spi.operation.AbstractOperation

org.linuxforhealth.fhir.operation.bench.BenchOperation

All Implemented Interfaces:

FHIROperation

public class BenchOperation
extends AbstractOperation

Custom operation to consume some CPU load to help out with understanding the relative performance of systems. This is particularly useful deploying in a cloud environment like K8s where the worker nodes are virtual, so you don't really know how much capacity a vCPU actually gives you. The operation has 2 parameters: threads - how many threads to spin up size - how much "work" to perform

Method Detail

buildOperationDefinition

protected OperationDefinition buildOperationDefinition()

Specified by:

buildOperationDefinition in class AbstractOperation

isAbstractResourceTypesDisallowed

protected boolean isAbstractResourceTypesDisallowed()

Description copied from class: AbstractOperation

Determines if the operation disallows abstract resource types, Resource and DomainResource. TODO: Remove this method when Issue #2526 is implemented, at which time, abstract resource types will be disallowed for any operation.

Overrides:

isAbstractResourceTypesDisallowed in class AbstractOperation

Returns:

true or false

doInvoke

protected Parameters doInvoke(FHIROperationContext operationContext,
                              java.lang.Class<? extends Resource> resourceType,
                              java.lang.String logicalId,
                              java.lang.String versionId,

                              FHIRResourceHelpers resourceHelper,
                              SearchHelper searchHelper)
                       throws FHIROperationException

Description copied from class: AbstractOperation

This is the method that concrete subclasses must implement to perform the operation logic.

Specified by:

doInvoke in class AbstractOperation
