Subject Pluggable Trigger Feed Event Provider
Date Fri, 08 Feb 2019 17:11:15 GMT
Hello Whiskers.

On Wednesday's Community Call, I presented my work on building a "pluggable
trigger feed event provider". The background for this experiment was
needing to build another trigger feed event source without having to
replicate all the boilerplate needed for trigger management.

Here is the presentation from the call:
https://speakerdeck.com/jthomas/apache-openwhisk-pluggable-event-providers
Video recording of the call is available on the OpenWhisk YouTube channel:

Feedback on the call was very positive so I've pushed the code to an
external Github repo allowing others to have a look at how it works.

This is the repo for the "generic event feed provider". The README contains
all the instructions on how to create a plugin and run the provider with a
pluggable event source.

Here's an example event plugin I built for an S3-compatible object store.
It polls a bucket endpoints and compares file etags, stored in Redis, to
determine any file changes. Triggers are fired with file events.

As discussed on the call, my next steps were....

   -

   Make the code public for the community to evaluate. (DONE ✅)
   -

   Write a few more plugin providers (RabbitMQ, MQTT) to test it further.
   -

   Contribute the code back to Apache to become an official component of
   the project.

All feedback welcome!
