What is the meaning of time in a distributed system? How can we make sense of events separated by great spans of space-time? Why do I need to give Riak a vector clock with every write? How do vector clocks even work?

This talk is the history of how we have tried to make sense of time, ordering, and causality in Riak, the trade-offs associated with each solution, and representations of logical time we are investigating for future versions.
