    I was thinking about transaction processing, eg visa/blockchain. And here storing and sending almost full packet for signature instead of 32 bytes matters. For sessions this should…

    Cost is 100+ times bigger signature size and more cpu usage. If you process several k per second it matters

    Try g.ai. It's stupid fast and uses google indexes. Kagi? sometimes doesn't correctly parse intent, in Google thing you can just ask function doing this and gives you it, with exam…

    Bftree solves one non-obvious pain point - caching when your data set is random (the key is a hash) and the data is smaller than the page size. LSM reads are based on block size; s…

    I've tested with wal enabled, got deadlock several times, so looks raw for now

    It was 1 year ago. Around 15 tikv serves, 32 cpu, 128 ram each, 4 tb nvme. In this case latency matters a lot. When i had load server in different region with ping of 3ms I got 70k…

    Tidb should handle it nice. I've wrote 200к inserts / sec for hour in peak. Underlying lsm works better for writes

    Also, won't most of the lib be removed due to dead code elimination? And used code will be inlined where applicable, so nothing to dedup in reality

    Rust can set restricts to all pointers, because 1 mut xor many shared refs rule. Borrow checker empowers this. https://en.wikipedia.org/wiki/Restrict

    What the point, though? You will get compiling code, but later you would need to reachitecture code to avoid violating rust rules.

    Retry is fine, but imagine being unable to pay for something within 10 minutes in month. And 10m in 1M is 99.98% sla. So it depends
