  Upcoming in Rails 7.1, you can specify a custom compressor for your cache, out of the box. See the `:compressor` option of `ActiveSupport::Cache::Store.new`:

  If that compression is internal-only, i'd start looking at zstd, which is much better at both speed and compression level

  Important to understand about Brotli vs. other compression is that Brotli has been pretrained with HTML/CSS/JS code. It efficiently compresses English text and source code, especially small files, due to its static dictionary.

  There are other factors that make Brotli good, but this is good to understand when dealing with web frontends.
