Michael McCandless commented on LUCENE-4120:
--------------------------------------------
bq. As for fst packing, the idea is fairly simple – you reduce the overall size
of the fst by moving states which have lots incoming arcs to offsets which
compress well (in vcoding).
That's all I did, inspired by your talk/paper... I think we could do more :)
> FST should use packed integer arrays

> There are some places where an int[] could be advantageously replaced with a
> packed integer array.
> I am thinking (at least) of:
> * FST.nodeAddress (GrowableWriter)
> * FST.inCounts (GrowableWriter)
> * FST.nodeRefToAddress (read-only Reader)
> The serialization/deserialization methods should be modified too in order to
> take advantage of PackedInts.get{Reader,Writer}.
