[GitHub] [arrow-datafusion] alamb opened a new issue #497: explain verbose doesn't include the output of all optimizer passes
alamb opened a new issue #497:
URL: https://github.com/apache/arrow-datafusion/issues/497
**Describe the bug**
`explain verbose` does not appear to show the output of each optimizer pass, nor does it seem to show pushed down predicates in the physical plan
**To Reproduce**
```shell
echo "true" > /tmp/foo.csv
cargo run -p datafusion-cli --no-default-features
```
Then run this SQL:
```sql
CREATE EXTERNAL TABLE foo(bar boolean)
STORED AS CSV
LOCATION '/tmp/foo.csv';
0 rows in set. Query took 0 seconds.
```
```sql
> explain verbose select * from foo where bar = true;
+-----------------------------------------+--------------------------------------------------------------------------+
| plan_type | plan |
+-----------------------------------------+--------------------------------------------------------------------------+
| logical_plan | Projection: #bar |
| | Filter: #bar Eq Boolean(true) |
| | TableScan: foo projection=None |
| logical_plan after projection_push_down | Projection: #bar |
| | Filter: #bar Eq Boolean(true) |
| | TableScan: foo projection=Some([0]) |
| logical_plan after projection_push_down | Projection: #bar |
| | Filter: #bar Eq Boolean(true) |
| | TableScan: foo projection=Some([0]) |
| physical_plan | ProjectionExec: expr=[bar] |
| | FilterExec: bar = true |
| | CsvExec: source=Path(/tmp/foo.csv: [/tmp/foo.csv]), has_header=false |
+-----------------------------------------+--------------------------------------------------------------------------+
```
**Expected behavior**
I expect to see plans after filter pushdown and constant folding. Instead I see two entries for `logical_plan after projection_push_down` which does not seem right
**Additional context**
Add any other context about the problem here.
