gRPC Tapping Filter with Hardware Acceleration in Service Mesh

Explore the implementation of gRPC tapping filters with hardware acceleration in service mesh environments. Learn about the challenges of monitoring upstream and downstream traffic in microservice architectures, particularly when using Envoy as a routing entity with TLS. Discover how the streaming gRPC Sink for transport socket level tapping addresses bottleneck issues in high-traffic scenarios and provides counters for traced traffic. Examine the ConnectionInfo cache replay mechanism and understand how memory copy operations can be offloaded to hardware accelerators to improve performance in memory-intensive tapping filter scenarios.
