HRW.Weighted (hrw v0.2.0)

Copy Markdown

Weighted HRW implementation for ensuring certain nodes get a greater share of keys.

Inspired by https://www.ietf.org/archive/id/draft-ietf-bess-weighted-hrw-00.html

Works with both flat lists (HRW.owner(key, [{"a", 1}, {"b", 4}], scorer: %HRW.Weighted{})) and skeletons (HRW.build([...], scorer: %HRW.Weighted{})).
