Class JavaJournalPerfSpec

  extended by akka.persistence.japi.journal.JavaJournalPerfSpec
All Implemented Interfaces:
JournalPerfSpec, JournalSpec, PluginSpec, TestKitBase

public class JavaJournalPerfSpec
extends java.lang.Object
implements JournalSpec, JournalPerfSpec


Java / JUnit consumable equivalent of JournalPerfSpec and JournalSpec.

This spec measures execution times of the basic operations that an PersistentActor provides, using the provided Journal (plugin).

It is *NOT* meant to be a comprehensive benchmark, but rather aims to help plugin developers to easily determine if their plugin's performance is roughly as expected. It also validates the plugin still works under "more messages" scenarios.

The measurements are by default printed to System.out, if you want to customise this please override the info() method.

The benchmark iteration and message counts are easily customisable by overriding these methods:

   public long awaitDurationMillis() { return 10000; }

   public int eventsCount() { return 10 * 1000; }

   public int measurementIterations { return 10; }

In case your journal plugin needs some kind of setup or teardown, override the beforeAll or afterAll methods (don't forget to call super in your overriden methods).

JournalSpec, param: config configures the Journal plugin to be tested
