  • simdjson

    Parsing gigabytes of JSON per second : used by Facebook/Meta Velox, the Node.js runtime, ClickHouse, WatermelonDB, Apache Doris, Milvus, StarRocks

    The author knows C++ (https://github.com/simdjson/simdjson) and writes a lot about his performance experiments. I don't see why he - or anybody else - shouldn't raise such questions and arguments without having people (like you) getting angry about it. Is it offensive?

    Anyway, he has a point, `cout` is used extensively as a logging mechanism. If you don't see that "single millisecond" making any difference, you certainly haven't work on a relevant system.

  • InfluxDB
