tiden_examples

Playground for Tiden Ignite examples before publication.

Install pre-requisites

Install Tiden from Test PyPi:

    sudo -H pip3.7 install --index-url https://test.pypi.org/simple/ tiden

Alternatively, you can install Tiden from sources:

    git clone git@github.com:gridgain/tiden.git
    cd tiden
    bash ./build.sh
    bash ./install.sh

Checkout examples

To clone this example git repository you must have Git Lfs installed. https://git-lfs.github.com/

    git clone git@github.com:gridgain/tiden_examples.git
    cd tiden_examples

Running test suites

Provision hosts for running the test

Use your favourite means to provision some hosts for running the test - bare metal, AWS, docker.

Create config/env_${USER}.yaml file and put provisioned hosts into it. Unless config/env_${USER}.yaml exists, config/env_default.yaml will be used. Tune servers_per_host and clients_per_host according to your means.

environment:
    server_hosts:
      - <IP address 1>
      ...
      - <IP address N>
    servers_per_host: 1
    client_hosts:
      - <IP address 1>
      ...
      - <IP address N>
    clients_per_host: 1

Hosts should be accessible via SSH private key. You should put remote name and path to your environment config.

environment:
    username: ${USER}
    private_key_path: ${HOME}/.ssh/id_rsa

Create remote folder at the same location at all hosts, for example: /home/${USER}/tests.

environment:
    ...
    home: /home/${USER}/tests

Install your favourite JDK at all hosts at the same location, for example /usr/local/lib/java-8-oracle.

Remote JAVA_HOME can be set in the environment config as follows:

environment:
    ...
    env_vars: 
        JAVA_HOME: /usr/local/lib/java-8-oracle
        PATH: $JAVA_HOME/bin:$PATH

Run examples suite

Examples suite shows up simple test scenarios based on GeneralTestCase and AppTestCase.

    bash ./run_examples.sh

Run gatling suite

Gatling suite uses custom application and plugin to build and run Gatling scenario against Ignite instance REST API.

    bash ./run_gatling.sh

Additionally, you may collect async profiler information from Ignite nodes under load. For that, make sure kernel settings are tuned properly at your remote hosts:

• sys.kernel.perf_event_paranoid = 1
• sys.kernel.kptr_restrict = 0

See https://github.com/jvm-profiling-tools/async-profiler#basic-usage for more information

    bash ./run_gatling_with_flamegraph.sh
