A mock implementation of Hubble API

This project contains an implementation of Hubble API that can run as a server for various testing purposes.

There is a standalone main function in server/, and a package that can be called from tests or somehow otherwise in observer/.

Features:

• support for plain and compressed JSON files (i.e. .json & .json.{gz,bz2,xz})
• all flows events in a given set of JSON files are replayed to every client with adjusted timestamps
• distance between consequetive flow event timestamps is respected
  • speed adjustment can be applied, e.g. -10 to slow down 10x, 250 to speed-up 200x
