Aeron Community MeetUp London, May 2024 - Handling Data Loss

Martin Thompson, creator of Aeron, discusses data loss in network communication, comparing reliable TCP (like a phone call) to faster but unconfirmed UDP (like a postcard).

With UDP, custom solutions are needed to handle loss, especially for performance-critical applications like Aaron. Strategies include data sequencing, negative acknowledgments (NACs), and high watermarks.

These methods become trickier in multi-receiver scenarios to avoid overwhelming the network with retransmissions. Improvements in Aaron address handling large data loss in high-latency environments by delaying NACs and optimizing retransmission responses, reducing congestion, and improving overall data recovery.
