> 1D points already have an optimized merge implementation which works when points come in order. So maybe we could make IndexWriter's PointValuesWriter sort before feeding the PointsFormat and somehow propagate the information to the PointsFormat?
> The benefit is that flushing could directly stream points to disk with little memory usage.
