}

Example 2 with Activity

use of io.nosqlbench.engine.api.activityapi.core.Activity in project nosqlbench by nosqlbench.

the class ScenarioController method stop.

/**
 * Stop an activity, given the name by which it is known already in the scenario. This causes the
 * activity to stop all threads, but keeps the thread objects handy for starting again. This can be useful
 * for certain testing scenarios in which you want to stop some workloads and start others based on other conditions.
 *
 * Alternately, you can provide one or more aliases in the same command, and all matching names will be stopped.
 *
 * @param spec The name of the activity that is already known to the scenario
 */
public synchronized void stop(String spec) {
    logger.debug("request->STOP '" + spec + "'");
    List<String> aliases = Arrays.asList(spec.split("[,; ]"));
    List<String> matched = aliases.stream().map(String::trim).filter(s -> !s.isEmpty()).flatMap(aspec -> getMatchingAliases(aspec).stream()).collect(Collectors.toList());
    for (String alias : matched) {
        ActivityDef adef = aliasToDef(alias);
        scenariologger.debug("STOP " + adef.getAlias());
        stop(adef);
    }
}

Example 3 with Activity

use of io.nosqlbench.engine.api.activityapi.core.Activity in project nosqlbench by nosqlbench.

the class CoreServices method getOutputDispenser.

    OutputDispenser outputDispenser = new SimpleConfig(activity, "output").getString("type").flatMap(OutputType.FINDER::get).map(mt -> mt.getOutputDispenser(activity)).orElse(null);
    if (outputDispenser == null) {
