# Rationale for this change
Noticed while working on https://github.com/apache/arrow-datafusion/pull/3822
The `show all` command added by @waitingkuo in
https://github.com/apache/arrow-datafusion/pull/3455 is awesome!
When I do `show all` I am trying to verify the setting of a particular
configuration option. As coded now, the output comes out in some random order
(hash value I suspect):
Before:
```shell
❯ show all;
+-------------------------------------------------+---------+
| name | setting |
+-------------------------------------------------+---------+
| datafusion.execution.coalesce_target_batch_size | 4096 |
| datafusion.optimizer.filter_null_join_keys | false |
| datafusion.explain.physical_plan_only | false |
| datafusion.explain.logical_plan_only | false |
| datafusion.execution.coalesce_batches | true |
| datafusion.execution.batch_size | 8192 |
| datafusion.optimizer.skip_failed_rules | true |
| datafusion.execution.time_zone | UTC |
+-------------------------------------------------+---------+
11 rows in set. Query took 0.005 seconds.
```
After:
```shell
❯ show all;
+-------------------------------------------------+---------+
| name | setting |
+-------------------------------------------------+---------+
| datafusion.execution.batch_size | 8192 |
| datafusion.execution.coalesce_batches | true |
| datafusion.execution.coalesce_target_batch_size | 4096 |
| datafusion.execution.time_zone | UTC |
| datafusion.explain.logical_plan_only | false |
| datafusion.explain.physical_plan_only | false |
| datafusion.optimizer.filter_null_join_keys | false |
| datafusion.optimizer.skip_failed_rules | true |
+-------------------------------------------------+---------+
