vertx-redis-client (3.9.1) RedisAPI.get not getting any response.

[Tuhin Subhra Mandal]

Hi I am using vertx-redis-client and creating a pool.

My requirement is to check for the key in redis. If it does not exist, need to prepare some key, value and push it to redis.

The way I am doing it is as follows:

When I make a call to check ping, or the get key call, the thread is blocked for a long time, and async handler does not return any result. I am able to see that connection is getting established.

----------------> WARNING: Thread Thread[vert.x-eventloop-thread-0,5,main]=Thread[vert.x-eventloop-thread-0,5,main] has been blocked for 4278 ms, time limit is 20 ms

Future<Redis> redisPoolFuture = RedisVertx.createRedisPool (vertx, config);

redisPoolFuture.onSuccess (pool -> {
    RedisAPI redis = RedisAPI.api (pool);
    pool.send (Request.cmd (Command.PING), pingHandler -> {
        System.out.println ("========================> " + pingHandler.result ());
    });
    redis.get ("tuhin-key1", ah -> {
        System.out.println ("------------------> " + ah.result ());
    });
});



// Here is the method that generates redis pool

public static Future<Redis> createRedisPool(Vertx vertx, Config config) {

    return Future.future (promise -> {
        Redis redisPool = Redis.createClient (
                vertx,
                new RedisOptions ()
                        .setConnectionString ("redis://localhost:6379")
                        // allow at max 16 connections
                        .setMaxPoolSize (16)
                        // allow 32 connection requests to queue waiting
                        // for a connection to be available.
                        .setMaxWaitingHandlers (32));
        promise.complete (redisPool);
    });
}
