I am trying to explore the Aeron, I have a cluster of three nodes in my machine. What I am trying is setting up a simple model: one channel publisher in Node 1, and two channel subscriptions in Node 2, and Node 3.
Three of them are trying to communicate via multicast address as below:
- Node 1: Broadcast to aeron:udp?endpoint=239.255.255.1:4300|interface=192.168.64.6|ttl=16
- Node 2: Starting Receive... channel: aeron:udp?endpoint=239.255.255.1:4300|interface=192.168.64.5|ttl=16
- Node 3: Starting Receive... channel: aeron:udp?endpoint=239.255.255.1:4300|interface=192.168.64.4|ttl=16
I don't understand the result of attached image. Node 1 Publisher is trying to publish as fast as possible into the channel, unfortunately Node 2 and Node 3 are not consuming at the same time, there is only one consuming data at a time... In the screenshot below, node 2 always catchup the publisher, but Node 3 receive a few hundred of messages and then be hanged until Node 2 is completed 1 million of messages firstly. Are there any thing I missed? However if I reduce the frequency of publisher to 1 message per second, for example, then I can see both subscribers Node 2 and Node 3 are receiving messages same time.
The implementation of code: The publisher code: https://github.com/cseblog/aeron-demos/blob/main/aeron-multicast-ping-demo/src/main/java/org/multicast/Main.java
The Subscriber code: https://github.com/cseblog/aeron-demos/blob/main/aeron-multicast-pong-demo/src/main/java/org/multicast/Main.java
I am looking to understand this issue
