Replay is a tool for replaying logged actions in live time. It’s useful for simulating load on a develpoment or test system.
You need two things:
- A function or generator which returns a sequence of tuples of (timestamp, data). It’s strongly advised that you use a generator.
- A function which accepts the data and does something with it.
If you feed these into replay.mapc_time, it will fire your
processing function in live time – the time delta between the
timestamps from your seq is the delay in between calls to your
processing function.
See examples/ for a real-world use case, replaying Apache logs
against a test server.
