Thank you.

It can be merged.

If you still want to improve the code there are few possible changes:

• Rename the db associated with phoenix as state (or else) to make the code less confusing with the oar db.
• As it is a brand new python file we might add some typing.
• Use a the python logger instead of doing it manually.
