An Alternator user was recently "bit" when switching `alternator_enforce_authorization` from "false" to "true": ְְְAfter the configuration change, all application requests suddenly failed because unbeknownst to the user, their application used incorrect secret keys. This series introduces a solution for users who want to **safely** switch `alternator_enforce_authorization` from "false" to "true": Before switching from "false" to "true", the user can temporarily switch a new option, `alternator_warn_authorization`, to true. In this "warn" mode, authentication and authorization errors are counted in metrics (`scylla_alternator_authentication_failures` and `scylla_alternator_authorization_failures`) and logged as WARNings, but the user's application continues to work. The user can use these metrics or log messages to learn of errors in their application's setup, fix them, and only do the switch of `alternator_enforce_authorization` when the metrics or log messages show there are no more errors. The first patch is the implementation of the the feature - the new configuration option, the metrics and the log messages, the second patch is a test for the new feature, and the third patch is documentation recommending how to use the warn mode and the associated metrics or log messages to safely switch `alternaor_enforce_authorization` from false to true. Fixes #25308 This is a feature that users need, so it should probably be backported to live branches.

Key Guidelines for Contributors
- The user documentation is written in reStructuredText (RST) - a plaintext markup language similar to Markdown. If you're not familiar with RST, see ScyllaDB RST Examples.
- The developer documentation is written in Markdown. See Basic Markdown Syntax for reference.
- Follow the ScyllaDB Style Guide.
To prevent the build from failing:
-
If you add a new file, ensure it's added to an appropriate toctree, for example:
.. toctree:: :maxdepth: 2 :hidden: Page X </folder1/article1> Page Y </folder1/article2> Your New Page </folder1/your-new-article> -
Make sure the link syntax is correct. See the guidelines on creating links
-
Make sure the section headings are correct. See the guidelines on creating headings Note that the markup must be at least as long as the text in the heading. For example:

Building User Documentation
Prerequisites
- Python
- poetry
- make
See the ScyllaDB Sphinx Theme prerequisites to check which versions of the above are currently required.
Mac OS X
You must have a working Homebrew in order to install the needed tools.
You also need the standard utility make.
Check if you have these two items with the following commands:
brew help
make -h
Linux Distributions
Building the user docs should work out of the box on most Linux distributions.
Windows
Use "Bash on Ubuntu on Windows" for the same tools and capabilities as on Linux distributions.
Building the Docs
- Run
make previewto build the documentation. - Preview the built documentation locally at http://127.0.0.1:5500/.
Cleanup
You can clean up all the build products and auto-installed Python stuff with:
make pristine
