Allowing ISPs to charge for different levels of access to consumers
creates an uneven playing field for Internet-based companies.  As a
consumer, I already pay an ISP monthly to provide me a level of service when
accessing the internet.  I expect that access to be fair for all
companies so that I have equal access to all services on the Internet.

Allowing large companies to pay for faster "lanes" means that small
companies cannot compete fairly and hurts the normal pace of
innovation.  Please keep Net Neutrality in place so the Internet 
continues to be a place of innovation and not monied incumbents.

I want to build a system which uses rules. These rules will change hourly (i.e. "this rule is effective from 2pm to 6pm"). The rules must support arbitrarily complex logic on just 2-3 pre-defined variables and result in a boolean:

item.a > 10 && item.b == 0 || item.category == FOOTWEAR

These rules will be executed hundreds of times per second so I can't afford the overhead of plain old eval. I want to reload the current effective ruleset from the database hourly, precompile each rule's logic string and execute it via the quickest method possible. It might look something like this:

class Rule

git clone git://github.com/mperham/sidekiq
cd sidekiq && git checkout rails5
cd myapp && bundle
bundle exec sidekiq
# in another terminal tab
bundle exec rails s

Now hit http://localhost:3000/work to create a random set of jobs for sidekiq to perform.
