    Real world text editing traces for benchmarking CRDT and Rope data structures

  • Project mention: JSON-joy CRDT benchmarks, 100x speed improvement over state-of-the-art | | 2023-05-22

    Hey! Author of diamond types and the (linked) editing traces repository here. Would it be possible to make & share an editing trace or two from your application? Even a single user editing trace would be super helpful - like a big list of which objects were replaced by what values, in order.

    I really want json based CRDTs to be fast, but one of the problems we have optimising this stuff is that there arenโ€™t a lot of real world data traces around to use as baselines for benchmarking. I donโ€™t know which parts of automerge are slow, and without that knowledge I canโ€™t make them fast. If we have some data from your application, most upcoming json based CRDTs will almost certainly work well for your use case.

    If youโ€™re up for it, flick me an email or just open a PR on
