Integrated documentation for Ruby
# For context, this was inspired by the RubyRogues podcast #79 where they talked about
# documentation in Ruby, and specifically grumbled quite a bit about the failings of RDoc.
#
# http://rubyrogues.com/079-rr-documenting-code/
#
# As someone who's spent a lot of time using an IDE for programming C# and Java, I think
# Ruby could do a lot better at putting documentation at our fingertips as we program.
#
# Maybe making the documentation part of the structure of the code would facilitate this?

Introduction

  • Historically InnoDB development lags while MySQL is trying to GA
  • lots of things fixed in InnoDB since MySQL 5.0
  • important note -- plugin version of InnoDB is not the default in 5.1
