Hi Maurice, This is an interesting addition to the Bookkeeper! Thank you for contributing it back to the community. Can you share some performance data/charts to highlight benefits of this feature?
Also, is your workload write-heavy with reads mostly from the cold data? I imagine this option will increase latency of tailing reads (short delay, after the data made it to the disk).
