Nanoseconds may not matter yet, but they could be handy when for example we want to determine the order of parallel query executions. We are less than an order of magnitude away from being able to do 1M inserts/updates/deletes per second, so microseconds already are not always 100% reliable. We could possibly move to using LSNs fetched as part of the queries for this case, but this will surely introduce more problems than it solves :) Cheers ----- Hannu Krosing Google Cloud - We have a long list of planned contributions and we are hiring.
