1. Event Mesh Architecture: The company adopted a new event mesh architecture, which provided a more flexible and scalable event distribution framework. This architecture allowed for seamless integration of various event sources and consumers across different geographical locations.

       graph TD;
   	    A[Event Producer] -->|Event| B[Event Mesh];
   	    B --> C[Consumer 1];
   	    B --> D[Consumer 2];
   	    B --> E[Consumer 3];
   

2. AI-Driven Event Processing: They integrated AI-driven event processing capabilities, enabling real-time analysis and decision-making based on incoming events. This allowed for more personalized customer experiences and improved operational efficiency.

   import org.apache.kafka.clients.consumer.ConsumerRecord;
   import org.apache.kafka.clients.consumer.KafkaConsumer;
   import java.util.Collections;
   import java.util.Properties;
   
   public class AIEventProcessor {
       public static void main(String[] args) {
           Properties props = new Properties();
           props.put("bootstrap.servers", "localhost:9092");
           props.put("group.id", "ai-processor-group");
           props.put("key.deserializer", "org.apache.kafka.common.serialization.StringDeserializer");
           props.put("value.deserializer", "org.apache.kafka.common.serialization.StringDeserializer");
   
           KafkaConsumer<String, String> consumer = new KafkaConsumer<>(props);
           consumer.subscribe(Collections.singletonList("events"));
   
           while (true) {
               for (ConsumerRecord<String, String> record : consumer.poll(100)) {
                   // AI processing logic
                   System.out.printf("Processing event: %s%n", record.value());
               }
           }
       }
   }
