I'm using a an architecture as:Logs --> SpoolDir -->MemChannel --> AvroSink -->AvroSource --> MemChannel --> KafkaSink.I have a cluster with three kafka nodes and have created a topic with six partitions and replication factor one to make a POC.I have seen that 95% of the data goes to two partitions, these two partitions are in the same kafka node. I am not creating a "key" header on my events in Flume. So, reading the documentation the key is generated randomly. The messages are logs from different sources. Is it normal this behavior?
