When working with serverless actions, often we'll still need to access some sort of service, whether it's object storage, a database, or whatever. Here's a quick overview of how this works for IBM Cloud Functions (plus some gotchas ....) Continue reading
One of the best features of CouchDB is its change feed which allows us to get a feed of the changes happening on our database. It's also possible to have a serverless function (examples are for IBM Cloud Functions but should also work for Apache OpenWhisk) that fires in response to activity on that change feed. I have a database of events that I want to react to when they happen, but the change feed doesn't include the actual document that was added - but you can add one of the built-in functions to a sequence to make that happen.
