Adrien Grand commented on LUCENE-5751:
--------------------------------------
Hmm, should avgBPV be stored on a float? I think it can favor blocking too much
otherwise if eg. 8.9 becomes 8 in your heuristic. Otherwise, it looks good to
me!

> This one has fallen behind...
> It picks TABLE/GCD even when it won't actually save space or help, writes
> with BlockpackedWriter even when it won't save space, etc.
> Instead of comparing PackedInts.bitsRequired, factor in
> acceptableOverheadRatio too to determine "will save space". Check if blocking
> will save space along the same lines (otherwise use regular packed ints).
> Fix a similar bug in Lucene49 codec along these same lines (comparing
> PackedInts.bitsRequired instead of what would actually be written)
