"""
KEVEN Kafka Abstracts

This subpackage contains abstract base classes and utilities that form the backbone
of the Kafka messaging infrastructure. It includes:
  - Consumer server abstractions (e.g., KafkaConsumerServer)
  - Event handler abstractions (e.g., EventHandler, LongRunningEventHandler)
  - Event receiver/server abstractions (e.g., MessageReceiverServer, EventReceiverServer, AllEventsReceiverServer)
