As I was browsing through the Parquet code recently, I noticed that we depend on lzo where the Node bindings are MIT licensed but the underlying C library is GPL2. See schroffl/node-lzo#12

According to Wes Mckinney, apache/arrow#2209 (comment)

LZO isn't really used anymore (as soon as Snappy came around people largely stopped using it because of the *GPL licensing issues)

Just thought it would be worthwhile to make an issue about this while I was thinking about it.

I was trying to add LZO as an optional dependency but I suppose in that case we really should explain the licensing situation to users.

I am very open to removing LZO in 3.2. Supporting LZO on browsers will require a bunch of work anyways, and it is a huge dependency.
