Erlang Performance Lab demo – YouTube


By Erlang Central | Published: March 23, 2017



In this demo we visualise traffic within Elixir cluster. The cluster consists of two nodes ‘foo’ and ‘bar’ running the KV Server from the Elixir Getting Started tutorial [1]. The central circle represents the Internet. The other two circles represent ‘foo’ and ‘bar’ nodes. When we execute the demo_kv function, we start hitting the ‘foo’ node with requests to create buckets. As a result some buckets are created on the ‘foo’ node, but some are delegated to the ‘bar’ node. We can observe traffic flowing from the Internet to ‘foo’ and between ‘foo’ and ‘bar’.
