Andrew Lamb commented on ARROW-12306:
-------------------------------------
[~heymind] I think having the CsvExec be able to read from stdin (aka anything
that impl `Read`) is a good idea
Perhaps you an extend CsvFile
https://github.com/apache/arrow/blob/master/rust/datafusion/src/datasource/csv.rs#L50
so that it can take either a `Path` or something that implements `Read` and
then pass that information down to the `CsvExec`
> [Rust] Read CSV format text from stdin or memory

> Hello,
> I'm building a command line tool that can run SQL queries on text files (csv,
> json-line ..) . But the `CsvExec` in datafusion can only read csv text from
> files currently. I have checked its inner implantation the csv reader in
> arrow, anything impl `Read` could be a valid input.

> Should this feature ( read csv from stdin) come with datafusion ? Or I just
> make it into my own crate.
