looking good!

I'm also interested to hear if this gave you any ideas about how we could improve the compact index gem for consumers, so their implementations could potentially be shorter/easier.

Is there any extra configuration needed to enable this? Wanted to test locally, but see this when trying to bundle install against it:

HTTP GET http://localhost:9292/private/versions
HTTP 404 Not Found http://localhost:9292/private/versions
Bundler::Fetcher::FallbackError: Gem::Net::HTTPNotFound: http://localhost:9292/private/versions

@technicalpickles shouldn't be, what's showing up in the server logs?

I'll revisit this once there's a version of sqlite for jruby that supports what I used here
