Dawid Weiss updated LUCENE-7922:
--------------------------------
Attachment: node.patch
Didn't run tests, but I don't think it'll cause any harm to remove it.
> Remove packed FST support?

> I've been looking at the FST code we have today. Complex to read, even more
> complex to modify. I think it could benefit if we cleaned it up a bit (there
> are a few issues out there already that mention this).
> The first baby step would be to remove the "packed" representation of FSTs --
> I searched the codebase and I don't see a single place where {{pack}} would
> actually be {{true}}. The overhead associated with node packing seems to be
> not worth it in practice (since most FSTs are already fairly small).
> It'd be a breaking API change, but it's probably something worth undertaking
> for 7.0, unless I'm missing some use cases.
