Why --from option is ignored when creating a new branch with --restore option?

[ytnobody]

I want to create a new branch with backup of specified branch.

However, from option seems to be ignored.

$ pscale backup list mydb stage
  ID (4)         NAME                      STATE     SIZE     CREATED AT     UPDATED AT     STARTED AT     EXPIRES AT          COMPLETED AT  
 -------------- ------------------------- --------- -------- -------------- -------------- -------------- ------------------- -------------- 
  xxxxxxxxxxxx   2024.08.27 16:20:00.829   success   151.3M   10 hours ago   10 hours ago   10 hours ago   1 day from now      10 hours ago  
  xxxxxxxxyyyy   2024.08.27 04:20:01.027   success   151.3M   22 hours ago   21 hours ago   22 hours ago   2 days from now     22 hours ago  
  xxxxxxxxzzzz   2024.08.26 16:20:01.191   success   151.3M   1 day ago      1 day ago      1 day ago      13 hours from now   1 day ago     
  xxxxxxxxXXXX  2024.08.26 04:20:01.057   success   151.3M   1 day ago      1 day ago      1 day ago      1 hour from now     1 day ago     

$ pscale branch create mydb mybranch-1 --from stage --restore xxxxxxxxxxxx --wait
Branch mybranch-1 was successfully created.

$ pscale branch show mydb mybranch-1 
  NAME         PARENT BRANCH   PRODUCTION   SAFE MIGRATIONS   READY   CREATED AT     UPDATED AT      
 ------------ --------------- ------------ ----------------- ------- -------------- ---------------- 
  mybranch-1   main            No           No                Yes     1 minute ago   15 seconds ago  

Why parent of mybranch-1 is main? And is this behavior spec of planetscale?

I think this is the correct behavior. In your example mybranch-1 is a restored backup of stage, which is a child branch of main, so mybranch-1 is also a child of main.

I see why it's confusing though. Perhaps pscale should throw an error when --from and --restore are used together.

An alternative might be to use the --seed-data flag to create a child of stage that contains the data from stage's most recent backup:

pscale branch create mydb mybranch-2 --from stage --seed-data

See https://planetscale.com/docs/concepts/data-branching

--seed-data option had works as I desired.
Thank you.
