Just for Apache Arrow itself, https://arrow.apache.org/docs/java/ compared to https://arrow.apache.org/docs/js/ or https://arrow.apache.org/docs/cpp/ doesn't look promising in terms of the documentation being usable.

That could be improved without fixing the whole JVM data ecosystem, but that's mostly up to JVM developers. It's unfortunate if the Spark developers using Arrow aren't contributing in this area (especially since many of them are being paid), but it's all open source and undoubtedly pull requests are welcome.

Congratulations on the 1.0 release, it's only going to keep getting better! Really exciting to be able to share data in-memory across languages.
