An Empty Kafka is a Sad Kafka
summary
Built tool called Cogen plugin integrates with JMeter and connects to schema registry (Confluent or Redpanda) to download AVRO/Proto/JSON schemas, let users tweak fields (including enums), and produce validated messages into Kafka or Redpanda. It can generate millions of AVRO messages from schema-driven templates, consume from topics and run assertions, and now auto-imports AsyncAPI files so channels become topics with no manual schema mapping.
