Kefu Chai 7abd263ee6 db/config.cc: do not respect sstable_format option
"me" sstable format includes an important feature of storing the
`host_id` of the local node when writing sstables. The is crucial
for validating the sstable's `replay_position` in stats metadata as
it is valid only on the originating node and shard (#10080), therefor
we would like to make the `me` format mandatory.

before making `me` mandatory, we need to stop handling `sstable_format`
option if it is "md".

in this change

- gms/feature_service: do not disable `ME_SSTABLE_FORMAT` even if
  `sstable_format` is configured with "md". and in that case, instead,
  a warning is printed in the logging message to note that
  this setting is not valid anymore.
- docs/architecture/sstable: note that "me" is used by default now.

after this change, "sstable_format" will only accept "me" if it's
explicitly configured. and when a server with this change joins a
cluster, it uses "md" if the any of the node in the cluster still has
`sstable_format`. practically, this change makes "me" mandatory
in a 6.x cluster, assuming this change will be included in 6.x
releases.

Fixes #16551

Key Guidelines for Contributors

Creating Knowledge Base Articles

The kb/ directory holds source files for knowledge base articles in the Knowledge Base section of the ScyllaDB documentation.

The kb/kb_common subdirectory contains a template for knowledge base articles to help you create new articles.

To create a new knowledge base article (KB):

  1. Copy the kb-article-template.rst file from /kb/kb_common to /kb and rename it with a unique name.
  2. Open the new file and fill in the required information.
  3. Remove what is not needed.
  4. Run make preview to build the docs and preview them locally.
  5. Send a PR with "KB" in its title.

Building User Documentation

Prerequisites

  • Python 3. Check your version with $ python --version.
  • poetry 1.12 or later
  • make

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

  1. Run make preview to build the documentation.
  2. 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
