Introduce configurable congestion control.#38
Merged
Conversation
The primary motivation for this (as of 2024/02/28) is increase availability for customers using PlayHT On-Prem appliance by adding quick retries in response to RESOURCE_EXHAUSTED errors.
This change allows customers to turn on one of an enumerated set of congestion control algorithms. We've implemented just one for now, STATIC_MAR_2024, which retries at most twice with a 50ms backoff between attempts. This is a dead simple congestion control algorithm with static constants; it leaves a lot to be desired. We should iterate on these algorithms in the future. The CongestionCtrl enum was added so that algorithms can be added without requiring customers to change their code much.
