  • A ZODB database instance is easy to maintain
  • periodic packing
  • ZODB is cutting-edge stuff, and it is used in several important projects
  • ZODB does not currently offer such a facility
  • 15 Apr 2008
  • daily packing is often perfectly appropriate
  • object databases can seem somewhat exotic
  • their hierarchical structure is a natural complement to the hierarchical nature of content management systems
  • cron job to
  • If, instead of having a script open your "Data.fs" directly, you are using a ZEO server
  • packing will be simpler
  • will also not require that your clients disconnect
  • Routine maintenance

  • In defence of one of the great Python frameworks of the past decade
  • ZCA rocks. It's an incredibly advanced and powerful way to build software
  • ZCA adds complexity. It demands that you swallow its core concepts up front (interfaces, adapters, utilities, events) and get to know them pretty well
  • people can do crazy things, usually doing as much harm as good
  • elegant frameworks like BFG or Pylons
  • That doesn't mean the ZCA is right for all situations
  • learning to use the ZCA effectively is a bit like learning a new programming language on top of Python. You need to "get" those concepts
  • For the ZCA itself, there is clearly an opportunity right now to evolve
  • My personal wish-list
  • advice for projects, such as Plone, that use the ZCA for extensibility and inversion-of-control
  • Don't let the ZCA be the first API that people see
  • don't assume everyone has yet reached ZCA mastery
  • ZCA as a building block
  • BFG does this very well

  • We're trying to do something similar with Dexterity and the ecosystem of tools around it
  • The same will hopefully be true for other technologies as we move towards Plone 5
  • improved integrator learning curve
