Cargo Features

Hudi has no features set by default.

[dependencies]
hudi = { version = "0.2.0-rc.1", features = ["datafusion"] }
datafusion = hudi-datafusion

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality may be removed in the future.
