Welcome to Mango to CouchDB and the ASF (see thread)

We’re excited to welcome Mango to CouchDB and the ASF this week. Mango is an API Layer for CouchDB with a MongoDB inspired query language interface for Apache CouchDB which got donated to the ASF by IBM Cloudant. The codes is located here, a GitHub mirror should be available anytime soon.

Update handlers (see thread)

Question: a user had thought that updates were automatically called upon submitting or modifying a document to the DB, but then realised that to make an update run, they need to call its URL. They asked if there’s a way to achieve what they need or if they better add the logic to their server side code.


  • Update handlers need to be requested explicitly.
  • CouchDB doesn’t provide any method to change your documents automagically on PUT. It’s not oblivious how this feature should work
    in case of replication.
  • Normally, you don’t need any server side. All you need is to ensure
    that the clients are send you valid documents (e.g. setup validate_doc_update functions). Whether they call update handlers or they implement update handle logic on their side is not a question users should be concerned about – but valid data is.

Time to relax!

  • “But I look back and feel grateful for those trials and what they’ve taught me. They’ve forced me to grow and made me a better person. Most importantly, they taught me one of the hardest and most important lessons I’ve learned in my life: Seek to live with an open palm.”The weight is a gift
