The std feature enables features which require the standard library, namely `AHashMap` and `AHashSet`. DataFusion currently only uses `AHasher`, `CallHasher`, and `RandomState`, none of which require the standard library. This gives more control to projects depending on datafusion to minimize the amount of code they depend on. [1]: https://github.com/tkaitchuck/aHash/blob/e77cab8c1e15bfc9f54dfd28bd8820c2a7bb27c4/Cargo.toml#L24-L25 * Turn off default features of chrono as they're not needed In fact, the "oldtime" feature is [considered deprecated][1] and only included by default for backwards compatibility. The other features don't appear to be used by datafusion or ballista, so this gives projects depending on these crates more flexibility in what they choose to include.
