Message Recording and Playback

[fussel178]

Let's write a service which records and plays back the recorded messages on the eventbus.

Useful features

• [x] recording of published messages on the eventbus
• [ ] a filter which eventbus channels should be recorded
• [ ] a "playback" which publishes the recorded messages back on the eventbus
• [ ] selective playback (choose which channel to play back)
• [ ] record and play back the messages in the same time slices (maybe record message timestamps, too?)
• [ ] storage and access support for different locations (like filesystem, database, etc.)
• [ ] dynamic start and stop of recording and playback during operation
• [ ] progress report on playback
• [ ] playback of a predefined time period
• [ ] a widget for the Telestion Client commons library (specified there)
• [ ] write unit tests
• [ ] write some examples

Things to consider

• multiple verticles for recording and playback
• define a unified storage interface (which can put and request data + timestamps)

I was thinking about a feature that enables regex filtering of the incoming messages . It could be useful to generate smaller "bag"-files in some specific cases, when not all the published messages on a specific address are vital.

That would be nice 👍

If you want to do that, @fussel178 should add it to the steps you can implement :)
