To Read

The RabbitMQ stream protocol supports multi-producers and multi-consumers per TCP Connection.
This version introduces the connection pool for Consumers and Producers.

There is a new ConnectionPoolConfig setting:

       new StreamSystemConfig
        {
            ConnectionPoolConfig = new ConnectionPoolConfig()
            {
                ConsumersPerConnection = 10, 
                ProducersPerConnection = 10, 
            }
        };

ConsumersPerConnection == The number of consumers per connection min 1 max 255 default is 1
ProducersPerConnection == The number of producers per connection min 1 max 255 default is 1

Each connection can handle different streams; see the image:

Performances

Sharing the same connection for multiple streams reduces the number of connections, but it could impact the performances:

• Consumer side. If one consumer is slow, it can also affect the other consumers
• Producer side: If all the producers are at full-rate, it can reduce the performances

The proper parameter depends on your environment.

Tip

You can use different StreamSystemConfig like:

configToReduceTheConnections = new StreamSystemConfig
        {
 ConnectionPoolConfig = new ConnectionPoolConfig()
            {
                ConsumersPerConnection = 50, // high value 
                ProducersPerConnection = 50,  // high value
            }
}

configToIncreaseThePerformances = new StreamSystemConfig
        {
 ConnectionPoolConfig = new ConnectionPoolConfig()
            {
                ConsumersPerConnection = 1, // low value 
                ProducersPerConnection = 1,  // low value
            }
}

There are many combinations from 1 to 255.
