Frequently Asked Questions

Where can I find more information?

See the datafusion-cli documentation for further information.

How do I make my IDE work with datafusion-cli?

“open” the datafusion/datafusion-cli project as its own top level project in my IDE (rather than opening datafusion)

The reason datafusion-cli is not part of the main workspace in datafusion Cargo.toml file is that datafusion-cli is a binary and has a checked in Cargo.lock file to ensure reproducible builds.

However, the datafusion and sub crates are intended for use as libraries and thus do not have a Cargo.lock file checked in.
