Add Documentation for Sorting by Create Time

[psavidis]

Acceptance Criteria (Required on creation)

• Add the description of the new parameter and the affected APIs.

• Mention how create-time column with null values might be influenced by the different db-vendors & state that users can manipulate the column themselves if they want more fine-grained control of create time.

  • Statement should be similar to "You can update external task rows in the database with a custom create time to influence the ordering of external tasks created with versions < 7.21.0"

• The above can be added in the Fetch External Tasks by Priority section. Rename it and use the same section both for priority & create-time

Yes, i've updated the status to reflect it 👍

[mboskamp]

I will do a review when the implementation is ready. We can't merge the documentation before (they will be published on merge) and in case we need to change the documentation this saves us an additional PR.

[psavidis]

Reopening to align the documentation examples to latest code changes.

[mboskamp]

Reopen because there is an issue with the OpenAPI examples.

[mboskamp]

The fix for the OpenAPI looks good 👍

After latest agreements to use sorting field instead of sortings, this task can be considered closed since there is no change in the documentation. The field change will be part of another separate task, part of the parent ticket.

Closing the ticket as done.
