Yonik Seeley commented on LUCENE-3298:
--------------------------------------

Perhaps we should just have two implementations (a 32 bit one, and a 64 bit one)?

> The FST uses a single contiguous byte[] under the hood, which in java is indexed by int
so we cannot grow this over Integer.MAX_VALUE.  It also internally encodes references to this
array as vInt.
> We could switch this to a paged byte[] and make the far larger.
> But I think this is low priority... I'm not going to work on it any time soon.
