Leondon9 opened a new issue, #62695:
URL: https://github.com/apache/airflow/issues/62695
### Apache Airflow version
main (3.x)
### What happened
`airflow-ctl variables import` supports `--action-on-existing-key`
(`overwrite`/`fail`/`skip`), but `pools import` and `connections import`
hardcode `action_on_existence=FAIL`. This means importing pools or connections
fails if any entity already exists, with no way to overwrite or skip.
This is an inconsistency within the same package — all three commands use
the same `BulkActionOnExistence` enum and the same bulk API pattern, but only
`variables import` exposes the option.
For `connections`, this is also a regression from Airflow 2, which had
`--overwrite` on `airflow connections import`.
### What you think should happen instead
`pools import` and `connections import` should support
`--action-on-existing-key` (`overwrite`/`fail`/`skip`), matching the existing
`variables import` behavior.
### How to reproduce
```bash
# Export a pool, then try to re-import it — fails with no workaround
airflow-ctl pools export pools.json
airflow-ctl pools import pools.json # fails because pool already exists
# Same for connections
airflow-ctl connections export connections.json
airflow-ctl connections import connections.json # fails
```
### Operating System
Any
### Versions of Apache Airflow Providers
N/A
### Deployment
Other
### Deployment details
_No response_
### Anything else
**Root cause**: Three different developers implemented pool (May 28),
variable (May 29), and connection (Jul 1) import independently. Variable got
the `--action-on-existing-key` flag; pool and connection did not.
**References**:
- `ARG_VARIABLE_ACTION_ON_EXISTING_KEY` in `cli_config.py:270-276`
- `pool_command.py:116` — `action_on_existence=BulkActionOnExistence.FAIL`
- `connection_command.py:65` —
`action_on_existence=BulkActionOnExistence("fail")`
