Examples with RedisWrapper ai.grakn.engine.data.RedisWrapper used on opensource projects

Example 1 with RedisWrapper

use of ai.grakn.engine.data.RedisWrapper in project grakn by graknlabs.

the class EngineContext method before.

@Override
protected final void before() throws Throwable {
    RestAssured.baseURI = uri().toURI().toString();
    if (!config.getProperty(GraknConfigKey.TEST_START_EMBEDDED_COMPONENTS)) {
        return;
    }
    SimpleURI redisURI = new SimpleURI(Iterables.getOnlyElement(config.getProperty(GraknConfigKey.REDIS_HOST)));
    jedisPool = new JedisPool(redisURI.getHost(), redisURI.getPort());
    // To ensure consistency b/w test profiles and configuration files, when not using Janus
    // for a unit tests in an IDE, add the following option:
    // -Dgrakn.conf=../conf/test/tinker/grakn.properties
    // 
    // When using janus, add -Dgrakn.test-profile=janus
    // 
    // The reason is that the default configuration of Grakn uses the Janus Factory while the default
    // test profile is tinker: so when running a unit test within an IDE without any extra parameters,
    // we end up wanting to use the JanusFactory but without starting Cassandra first.
    LOG.info("starting engine...");
    // start engine
    setRestAssuredUri(config);
    spark = Service.ignite();
    config.setConfigProperty(GraknConfigKey.REDIS_HOST, Collections.singletonList("localhost:" + redis.port()));
    RedisWrapper redis = RedisWrapper.create(config);
    server = startGraknEngineServer(redis);
    LOG.info("engine started on " + uri());
}
