  • https://issues.apache.org/jira/browse/AIRFLOW-XXX
  • In case you are fixing a typo in the documentation you can prepend your commit with [AIRFLOW-XXX], code changes always need a Jira issue.

Description

Tests

Commits

• My commits all reference Jira issues in their subject lines, and I have squashed multiple commits if they address the same issue. In addition, my commits follow the guidelines from "How to write a good git commit message":
  1. Subject is separated from body by a blank line
  2. Subject is limited to 50 characters (not including Jira issue reference)
  3. Subject does not end with a period
  4. Subject uses the imperative mood ("add", not "adding")
  5. Body wraps at 72 characters
  6. Body explains "what" and "why", not "how"

Documentation

• In case of new functionality, my PR adds documentation that describes how to use it.
  • All the public functions and the classes in the PR contain docstrings that explain what it does
  • If you implement backwards incompatible changes, please leave a note in the Updating.md so we can assign it to a appropriate release

Can you add some documentation about this option? If there is no information about this feature in the documentation, very few people will be able to use it.

@mik-laj - > where do you think the documentation should be added ? Maybe you can provide some pointers? Most of the config options are documented in comments of the default_airlfow.cfg. Any other specific place you think this documentation should be added (and where all the previous options are documented?)

[mik-laj]

and where all the previous options are documented?

We have documentation gaps, but we try to develop documentation all the time. There is no precise documentation for the SLA mechanism, but this does not mean that it is impossible to write a few sentences and put them in the documentation. Another person who wants to describe the wider documentation will have less work.

I think that these two sentences describing this parameter may be placed in a new document in the howto directory. I will give an example of documentation that describes the configuration parameter.
