Andrew Lamb updated ARROW-9382:
-------------------------------
Description:
Currently we do not support boolean columns on groupBy.
Here is a reproducer:
{code}
alamb@MacBook-Pro:~/Software/arrow/rust$ echo "false" > /tmp/foo.csv
alamb@MacBook-Pro:~/Software/arrow/rust$ cargo run --bin datafusion-cli
Finished dev [unoptimized + debuginfo] target(s) in 0.14s
Running `target/debug/datafusion-cli`
> create external table test(c1 boolean) stored as CSV location '/tmp/foo.csv';
0 rows in set. Query took 0 seconds.
> select count(c1), c1 from test group by c1;
ArrowError(ExternalError(ExecutionError("Unsupported GROUP BY data type")))
{code}
The expected result is
{code}
1, false
{code}
was:Currently we do not support boolean columns on groupBy.
