> 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.
