how long can you time-travel? is this something like https://www.reddit.com/r/ruby/comments/15o9hc1/timetraveling_ruby_logger/ https://www.reddit.com/r/ruby/co

  Conceptually similar in that you can decide after-the-fact what state you want to see. But Time Travel Debugging applies that to everything in the program, not just log statements - all function calls, variables, memory locations, etc can be reconstructed after the fact without having to log them explicitly.

    Oh, and regarding how long - it depends how long it takes to fill the circular buffer of non deterministic behaviour. Serious compute bound workloads can run days with a gigabyte of non deterministic event log. Serious IO bound workloads burn it much faster. For a rule of thumb, think of it consuming a few MB per second, so the length of the time travel is limited by how much of that you can store.
