These arrays are in general a crazy costly part of using taxonomy facets ... we should explore more efficient alternatives. E.g. if the Lucene user is only using a single level hierarchy (field `foo` and value `bar`), maybe we could pre-allocate slices of ordinal space to each field `foo` which could be stored much more compactly (e.g. an interval tree) than the full `int[] parents` array we use today. -- This is an automated message from the Apache Git Service.
