jonmmease opened a new issue, #7624:
URL: https://github.com/apache/arrow-datafusion/issues/7624
### Describe the bug
When depending on datafusion-common with `default-features = false`, there
are compilation errors related to parquet functionality.
### To Reproduce
In the `datafusion-expr` crate, add `default-features = false` to the
`datafusion-common` dependency. Then try to build the `datafusion-expr` crate.
There are compilation errors such as:
```
error[E0433]: failed to resolve: use of undeclared crate or module `parquet`
--> datafusion/common/src/file_options/parse_utils.rs:20:5
|
20 | use parquet::{
| ^^^^^^^ use of undeclared crate or module `parquet`
error[E0433]: failed to resolve: use of undeclared crate or module `parquet`
--> datafusion/common/src/file_options/parquet_writer.rs:20:5
|
20 | use parquet::file::properties::{WriterProperties,
WriterPropertiesBuilder};
| ^^^^^^^ use of undeclared crate or module `parquet`
error[E0433]: failed to resolve: use of undeclared crate or module `parquet`
--> datafusion/common/src/file_options/parse_utils.rs:43:13

43 | ) -> Result<parquet::basic::Encoding> {
| ^^^^^^^ use of undeclared crate or module `parquet`
error[E0433]: failed to resolve: use of undeclared crate or module `parquet`
--> datafusion/common/src/file_options/parse_utils.rs:46:23
|
46 | "plain" => Ok(parquet::basic::Encoding::PLAIN),
| ^^^^^^^ use of undeclared crate or module
`parquet`
|
...
```
### Expected behavior
It would be possible to compile `datafusion-common` with the default
`parquet` feature disabled.
### Additional context
In VegaFusion I compile datafusion-common into WASM, and the `parquet` crate
is not (easily?) compatible with WASM due to some non-rust compression
dependencies.
I'll have a PR with suggested fix up shortly
