Benchmark Service

The Benchmark Service is a tool that allows measuring execution times of repeated GraphQL schema calls. It is intended for internal response time measurements, error handling is limited.

Prerequisites

  • Java 11
  • Maven

Using Benchmark Service

Configuration

The following settings need to be adjusted to the GraphQL Service in question:

service:
  url: localhost
  port: 8080
  endpoint: /graphql
  username: integrationservice_user
  password: integrationservice_user_password

The above snippet shows the settings for the local profile, intended for local assessment with the Integration Service which is part of this repository.

Currently, the application only supports basic auth.

Running a benchmark

  • Start the application, if using local profile, the application will use port 9000
  • Once the application is up and running, perform a post request:
    • schema refers to a schema stored in the application resources
    • numberOfCalls indicates the amount of calls to be performed. Calls will be done in a serial manner.
curl --location --request POST 'localhost:9000/benchmark' \
--header 'Content-Type: application/json' \
--data-raw '{
    "schema": "/schemas/benchmark.graphqls",
    "numberOfCalls": 20
}'
  • The response will provide a UUID that is needed to obtain the results:
HTTP/1.1 200 OK
...
Content-Type: application/json
{"id":"619c2b58-e661-4cda-b197-3b28fd7db5a8"}
  • Once the benchmark are running, results can be obtained under http://localhost:9000/results using two path parameters:
    • uuid (required): the uuid of the benchmark that was provided in the response of the post request
    • bucketSize (optional): the size of the buckets used to display the call response time distribution, defaults to 1000ms
    • Example: http://localhost:9000/results?uuid=6f3c4c4f-be7b-4c40-987e-5ea65d04a5&bucketSize=100
