Apache Geode Benchmarks

This project contains a benchmarking framework and benchmarks for Apache Geode. It is based on the yardstick framework, but with a java based test configuration and test execution framework.

These benchmarks are under development.

Running the benchmarks

The benchmarks require machines with passwordless ssh enabled in order to run, so ensure that the authentication key pair for SSH does not have a passphrase. If you have previously created a key pair with a passphrase, you can create a different key pair which is of a different type than the previously created one. Be sure to backup your existing key pair before creating a new one. The public key needs to be in PEM format, but some newer OpenSSH versions default to a new format. PEM format can be forced by using -m PEM:

ssh-keygen -m PEM -t rsa

While running a test on a single machine (i.e. localhost) add the generated key to authorized_keys to authorize the user:

cat <your_public_key_file> >> ~/.ssh/authorized_keys

Test if you can ssh to localhost:

ssh localhost

As long as that works, we are good to go.

Get your local hosts name:

hostname

Edit /etc/hosts and add the local host name with and without domain to localhost entries.

127.0.0.1 localhost mycomputer mycomputer.mydomain
::1       localhost mycomputer mycomputer.mydomain

To run all benchmarks, run the benchmark task and pass in a list of hosts.

For example:

./gradlew benchmark -Phosts=localhost,localhost,localhost,localhost

Options

The benchmarks can take configuration options. Some using Gradle's -P flag and other, which adjust benchmark behavior, via Java system properties using -D.

Option Description
-Phosts Hosts used by benchmarks on the order of client,locator,server,server (-Phosts=localhost,localhost,localhost,localhost)
-PoutputDir Results output directory (-PoutputDir=/tmp/results)
-Pbenchmark.X Where X is a benchmark configuration, defined below.
-Pbenchmark.R.X Applies properties to specific roles. Where R is the role, "client", "server", "locator", X is a benchmark configuration, defined below.
--tests Specific benchmarks to run (--tests=PartitionedPutBenchmark)
-d Debug
-i Info
-PtestJVM (Deprecated, use -Pbenchmark.withToolchainVersion) Path to an alternative JVM for running the client, locator, and servers. If not specified JAVA_HOME will be used. Note all compilation tasks will still use JAVA_HOME.

withGc Select which GC to use. Valid values CMS (default), G1, Z, Shenandoah, Epsilon. (optionally per-role)
withHeap Specify how large a heap the benchmark VMs should use, default "8g". Accepts any -Xmx value, like "32g". (optionally per-role)
withThreads Specify how many threads to use when executing the benchmark. Default varies by benchmark.
withWarmup Specify how long to warm up the benchmark in seconds. Default is 60 seconds.
withDuration Specify how long to run the benchmark in seconds. Default is 300 seconds.
withMinKey The minimum key value in the key range. Default is 0.
withMaxKey The maximum key value in the key range. Default varies by benchmark.
withLocatorCount Number of locators a topology should use. Typically defaults to 1.
withServerCount Number of servers a topology should use. Typically defaults to 2.
withClientCount Number of clients a topology should use. Typically defaults to 1.
withReplicas Number of region replicas.
withAsyncReplication Enable asynch region replication.
withNettyThreads Number of threads Netty IO Services should have.
Geode Benchmarks

These options only apply to Geode benchmarks.

Option Description
withSsl Flag to run geode with SSL. A self-signed certificate will be generated at runtime.
withSslProtocols Specifies enabled SSL protocols. See Geode property ssl-protocols
withSslCiphers Specifies enabled SSL chipher suites. See Geode property ssl-ciphers
withSecurityManager Flag to start Geode with the example implementation of SecurityManager
withSniProxy Use SNI proxy topology.
withSniProxyImage Provide an alternative Docker image coordinate for SNI proxy.
withRouter Use router with SNI proxy topology.
withRouterImage Provide an alternative Docker image coordinate for router.
Debugging

These options should not be used when measuring benchmarks.

Option Description
withValidation Enable validation of operations. Default disabled.
withGcLogging Enable GC logging. Default disabled.
withSafepointLogging Enable Safepoint logging. Default disabled.
withStrace Launch remote JVM via strace for tracing system calls. Default disabled.

Scripts for running in aws and analyzing results

This project includes some scripts to automate running benchmarks in AWS and analyzing the results produced (as well as the results produced from running locally). See the README.md in the infrastructure/aws directory.

Project structure

The project is divided into two modules

  • harness - Contains test framework code for running benchmarks. Does not depend on Apache Geode.
  • geode-benchmarks - Individual benchmarks of Apache Geode.

Sample benchmark

Benchmarks are defined in declarative configuration classes. Each configuration class is run as a junit test which calls the configure method and passes it to the TestRunner, which executes the test on the provided TEST_HOSTS.

Benchmarks are composed of before tasks, after tasks, and workload tasks. Each seperate before and after task is run once. Workload tasks are run repeatedly and their execution time is measured and reported by the yardstick framework.

/**
* Benchmark configuration class, which defines the topology of the test and
* the initialization tasks and workload tasks for the test.
*/
public class PartitionedPutBenchmark extends AbstractPerformanceTest {

  @Test
  public void run() throws Exception {
    TestRunners.defaultRunner().runTest(this::configure);
  }
  
  /**
  * Declare the configuration of the test by calling methods
  * on TestConfig.
  */
  public TestConfig configure() {
    TestConfig testConfig = new TestConfig();
    int locatorPort = 10334;

    //This test has three roles, a geode locator, server, and client
    config.role("locator", 1);
    config.role("server", 2);
    config.role("client", 1);
    
    //Define how the locator,server and client are initialized
    config.before(new StartLocator(locatorPort), "locator");
    config.before(new StartServer(locatorPort), "server");
    config.before(new StartClient(locatorPort), "client");
    config.before(new CreatePartitionedRegion(), "server");
    config.before(new CreateClientProxyRegion(), "client");
    //Define the benchmarked workload, which runs in a client
    config.workload(new PutTask());
    
    return config;
  }
}
/**
* Workload task, which extends the yardstick BenchmarkDriverAdapter
* 
* Workload tasks should execute a single unit of work, and will be run repeatedly
* for the duration of the test.
*/
public class PutTask extends BenchmarkDriverAdapter implements Serializable {
  private Region<Object, Object> region;
  
  @Override
  public void setUp(BenchmarkConfiguration cfg) throws Exception {
    super.setUp(cfg);
    ClientCache cache = ClientCacheFactory.getAnyInstance();
    region = cache.getRegion("region");
  }

  
  @Override
  public boolean test(Map<Object, Object> ctx) throws Exception {
    region.put(1,2);
    return true;
  }
}

SNI Proxy

You can run any benchmark on a topology that routes all client-server communication through an SNI proxy.

The withSniProxy property accepts:

  • HAProxy for HAProxy based SNI proxy (default).
  • Envoy for Envoy based SNI proxy.
  • Manual for providing your own SNI proxy and managing its lifecycle.

The withSniProxyImage property can be used to provide an alternative Docker image to one of the supported proxy implementations. The value should be set to a valid Docker image coordinate.

To run a test, e.g. PartitionedGetBenchmark, with default SNI Proxy:

./run_tests.sh -t anytagname -- -Pbenchmark.withSniProxy --tests=PartitionedGetBenchmark

Since SNI is a feature of TLS, running with the SNI topology incurs TLS overheads with implied -Pbenchmark.withSsl.

Router

An alternative topology uses a router sitting in front of the SNI proxy to simulate off network access to the cluster, enabled with -Pbenchmark.withRouter.

Enabling the router implies -Pbenchmark.withSniProxy.

The withRouter property accepts:

  • HAProxy for HAProxy based router (default).
  • Manual for providing your own router and managing its lifecycle.

Example:

./run_tests.sh -t anytagname -- -Pbenchmark.withRouter --tests=PartitionedGetBenchmark
