I am trying to connect to RabbitMQ cluster using nodejs library amqplib
I cannot find any information on connection string. I am trying var
amqp_url =
["amqp://admin:admin#172.26.126.248:5672/vhost_test","amqp://admin:admin#172.26.126.249:5672/vhost_test","amqp://admin:admin#172.26.126.250:5672/vhost_test"];
is there any other library supports cluster?

I have a local instance of Apache Kafka 2.0.0 , it running very well. In my test I produce and consume data from twitter and put them in a specific topic twitter_tweets and everything is OK. But now I want to consume the topic twitter_tweets with Kafka Connect using de connector Kafka Connect S3 and obviusly store the data in AWS S3 without using Confluent-CLI.
Can I do this without Confluent? Anyone have an example or something to help me?
without Confluent
S3 Sink is open source; so is Apache Kafka Connect.
Connect framework is not specific to Confluent
You may use Kafka Connect Docker image, for example, or you may use confluent-hub to install S3 Connect on your own Kafka Connect installation.
How to get all connected clients of a redis cluster?
I am using AWS elasticCache redis with non cluster mode and redission as my redis client.
My Use Case:
I need to run specific code from only 1 connected redis client.
Thanks
redis has command about client information like CLIENT LIST, check out this page .
you could checkout this page for the command redisson has not supported yet.
I am trying to connect our asp.net application through Stack exchange client to Redis Cluster, but I am getting an connection error shown below :
No connection is available to service this operation:
I am using the connection string :
< add key="SearchCacheRedisConnectionString" value="IP:6379,IP:6379,connectTimeout=1000,abortConnect=false,ConnectRetry=3,syncTimeout=500,keepAlive=180" />
I have used the same connection string to connect to a standalone redis instance and everything works perfectly.
Its only when i try to connect to a cluster ( 3 master 3 slave ) architecture that i am getting a connection error.
Is there a different connection string i am supposed to use to connect to a Redis Cluster or is there any specific changes i am supposed to make in my code to connect to a Cluster.
Any help will be much appreciated. Thank you
Could your connectTimeout be too low? The StackExchange.Redis default is 5000
I am using mosquito MQTT. I can connect to a single broker from my code and subscribe/publish for the same. I need to achieve a multiple broker connection from the code dynamically. How do I do that?
I'm having problems figuring out how to use the Jedis library to connect to a redis socket connection.
I know how to connect through a network port:
Jedis jedis = new Jedis("localhost");
//Jedis jedis = new Jedis(unix_socket_path="/tmp/redis.sock");
But the socket connection(second in the list) doesn't work. The commands looked simlair to redis-py(python client) but when I tried the same syntax it didn't work. I also looked through the jedis sourcecode on github but couldn't see anything. Any ideas?
I don't think Jedis support unix domain sockets.
The constructor with a single parameter only accepts a hostname (using default TCP port).
Java is portable. It is supposed to provide the same API on different platforms. Unix domain sockets are specific to Unix/Linux. So the Java standard API does not support unix domain sockets. There are separate Java packages for this, but AFAIK, Jedis do not use them.
