A team is horizontally scaling stateless collectors that receive OTLP over gRPC, but traffic keeps sticking to a single backend collector. What should it change first?

Question

Accepted Answer

A. Switch to an L7 load balancer that understands gRPC. The scaling guide warns that standard L4 load balancers may keep persistent gRPC connections pinned to one backend, negating scale-out. For OTLP over gRPC, an L7 load balancer that understands gRPC is the recommended solution. Option b is wrong because adding exporters does not solve inbound gRPC connection stickiness.
