  • RabbitMQ 4.2 introduces SQL filter expressions for streams, enabling broker-side message filtering.
  • Combining SQL filters with Bloom filters achieves filtering rates of over 4 million messages per second.
  • Broker-side filtering reduces network traffic and client-side processing overhead.
  • RabbitMQ Streams address the challenge of high-throughput event streams with irrelevant data.
  • Bloom filters skip non-relevant chunks, while SQL filters evaluate per-message predicates.
  • RabbitMQ's filtering capabilities surpass Kafka, which lacks broker-side filtering.
  • A sample e-commerce application demonstrates filtering 10 million events to find 10 high-value orders.
  • SQL filter expressions allow precise filtering based on event type, time, region, and other criteria.
  • Performance results show SQL filtering alone processes 404,645 messages/second, while Bloom + SQL reaches 4,868,549 messages/second.
  • Bloom filters improve performance by skipping irrelevant chunks before disk I/O.
