[GitHub] [arrow-datafusion] Dandandan opened a new issue #221: The non-verbose `EXPLAIN` statement doesn't show optimized logical plan
Dandandan opened a new issue #221:
URL: https://github.com/apache/arrow-datafusion/issues/221
**Describe the bug**
The `EXPLAIN` command is useful to show the plan of the query engine. However, the current output shows the un-optimized logical plan, which is not very useful as it maps almost 1:1 to the query.
**To Reproduce**
```sql
explain select price from example;
+--------------+--------------------------------------+
| plan_type | plan |
+--------------+--------------------------------------+
| logical_plan | Projection: #price |
| | TableScan: example projection=None |
+--------------+--------------------------------------+
1 rows in set. Query took 0 seconds.
```
**Expected behavior**
Explain without verbose should show a optimized non-verbose plan.
**Additional context**
