WebGRPC Connection Backoff Protocol When we do a connection to a backend which fails, it is typically desirable to not retry immediately (to avoid flooding the network or the server with requests) and instead do some form of exponential backoff. We have several parameters: INITIAL_BACKOFF (how long to wait after the first failure before retrying) gRPC calls can be interrupted by transient faults. Transient faults include: 1. Momentary loss of network connectivity. 2. Temporary unavailability of a service. 3. Timeouts due to server load.
