Antoine Pitrou commented on ARROW-9188:
---------------------------------------

Well, I'm not sure it's a good idea to disable Brotli and make some Parquet files unreadable (I suppose it's mainly used in Parquet, right?).

> I discovered by symbol sleuthing that even if the Brotli shared libraries are available on the system, the static libraries will be used for linking. Here's a dump of the symbols on my machine
> https://gist.github.com/wesm/b7e911424ce3ca3a175b652666fe6f89
> The largest of these symbols {{kBrotliDictionaryData}} is 120KB
> Since we statically link everything in our Python wheels, we might consider disabling Brotli in manylinux builds at least since it adds 800KB to libarrow.so
