Thanks @jonahgao
THere appear to be quite a few more uses of OnceLock in th code too:
https://github.com/search?q=repo%3Aapache%2Fdatafusion+OnceLock&type=code
Do you plan on moving them too?
I also linked this PR to #11687 which has a few other PRs linked as well that were in draft

Thats good point, wondering we probably want to use LazyLock in documentation generation |
