We present AdaptRaft, a variant of the Raft consensus algorithm that dynamically adjusts its timing parameters using a lightweight online learning model, reducing tail latency by up to 34% in geo-distributed deployments.
A modified Raft implementation with an online bandit learner that adapts election and heartbeat timeouts to observed network conditions. Companion codebase for the SOSP 2024 paper.
Informal notes clarifying which safety and liveness properties Raft provides under which assumptions, written while preparing a talk on adaptive consensus.
