If not configured at all, the grpc-timeout header is not used and gRPC requests time out like any other requests using timeout or its default. The primary focus is measuring the effect on performance of keepalive connections. “connect_timeout” is the time limit to get a connection to the upstream service. The initial Envoy migration effort focused on creating a new edge solution that offered feature parity with the existing stack, which included serving A/B deploys, bot detection, and CDN request. As a starting point, lowering the upstream timeout to 100ms will allow several retries, accounting for the jitter that Envoy adds between calls.

This API allows implementors to build a topology in which Envoy does not need to be aware of all upstream clusters at initial configuration time. io and how it enables a more elegant way to connect and manage microservices. On the other hand, if the request makes many parallel requests (“high fan-out”) without an aggressive global timeout, adding retries will result in consistently poor performance.
