URL: https://github.com/apache/arrow-datafusion/issues/937
**Is your feature request related to a problem or challenge? Please describe
what you are trying to do.**
While developing projects with datafusion, often times it is useful to
preview the output.
Right now it is somewhat awkward to print the results of a DataFrame to
`stdout` as it requires something like the following from the examples
```rust
let df = ctx
.read_parquet(filename)?
.select_columns(&["id", "bool_col", "timestamp_col"])?
.filter(col("id").gt(lit(1)))?;
let results = df.collect().await?;
pretty::print_batches(&results)?;
```
**Describe the solution you'd like**
it would be nice to allow a user to simply call a `show` function
```rust
let df = ctx
.read_parquet(filename)?
.select_columns(&["id", "bool_col", "timestamp_col"])?
.filter(col("id").gt(lit(1)))?;
df.show().await;
```
