SWIM: Tunable protocol period #5568

Open baumanj opened 5 years ago

baumanj commented 5 years ago

Since the relationship between protocol period Tʹ and connection latencies is vital to achieving the properties described in the SWIM paper, a facility for tuning the protocol period after compilation would be useful. #5975 describes how we should make this tunable at runtime.

If we determine that dynamic changes during runtime are necessary, we should implement a self-tuning value. The runtime could determine what the threshold should be based on the size of the mesh network and the latencies it's experiencing.

The worst-case message round-trip time (how long the algorithm waits for ack messages) should probably also be made tunable as part of this work.

An environment variable-based approach will be trivial with our EnvConfig abstraction.

Dynamic self-tuning is left as an exercise for the reader 😄
