I observed several trends at ApacheCon 2015, including a strong presence of Apache Kafka, with talks on its scalability, architecture, and integration with other frameworks such as Confluent Platform, Pulsar, and Apache NiFi. I also saw interest in emerging technologies like real-time analytics, stream processing, and data flow management systems. The Confluent Platform was showcased, including Schema Registry and Confluent's efforts to improve server utilization through resource allocation and isolation techniques. Additionally, the event highlighted collaborations between Confluent and other companies, such as Amazon Web Services, to simplify cloud services and data management. Overall, the conference demonstrated a growing interest in real-time stream processing technologies.
