The requirements for keyBy partitioning are a bit different: distribute keys across groups as evenly as possible (and there are much more keys than key groups). For materialization, selected values should be equi-distant from each other as much as possible (and there are much less backends than possible delay values). (AFAIK, murmur hash is used in keyBy partitioning) -- This is an automated message from the Apache Git Service.
