Fwiw this is standard procedure for anyone shipping a persistent storage product.

FoundationDB's testing turns the rigorous up to 11 and I'm unaware of anybody else who's published a description of a testing approach that goes to quite the same extremes.

If that's just because I haven't noticed the others, I'd love to hear about them for comparison.

  • I found a dataloss bug in the first hour of testing FDB. I think their testing hype is a bit overhyped.

    I also find it somewhat irritating that they won't take fixes or reports of problems with the storage engine because "we fixed this in redwood" when redwood is completely theoretical.

    • You've been able to use redwood since FDB 7.1 via ssd-redwood-1-experimental. Hardly theoretical.

      Curious about that data loss bug. do you have a link? most bugs I've seen have to due with latency spikes and cluster unavailability. haven't seen any around data loss after transaction has committed.
