Avi Kivity 9927c6a3d4 Merge 'Reapply "audit: enable some subset of auditing by default"' from Piotr Smaron
This reverts commit a5edbc7d612df237a1dd9d46fd5cecf251ccfd13.

<h3>Why re-enabling table audit</h3>

Audit has been disabled (scylladb/scylla-enterprise/pull/3094) over many concerns raised against the table implementation, e.g. scylladb/scylla-enterprise/issues/2939 / scylladb/scylla-enterprise/issues/2759 + there's whole outstanding backlog of issues . One of the concerns was also a possible loss of availability, and since then we migrated audit keyspace from SimpleStrategy RF=1 to NetworkTopologyStrategy RF=3 (scylladb/scylla-enterprise/pull/3399) and stopped failing queries when auditing fails (scylladb/scylla-enterprise/pull/3118 & scylladb/scylla-enterprise/pull/3117), which improves the situation but doesn't address all the concerns. Eventually we want to use syslog as audit's sink, but it's not fully ready just yet, and so we'll restore table audit for now to increase the security, but later switch to syslog. BTW. cloud will enable table audit for AUTH category scylladb/sre-ops-automation/issues/2970 separately from this effort.

<h3>Performance considerations</h3>

We are assuming that the events for the enabled categories, i.e. DCL, DDL, AUTH & ADMIN, should appear at about the same, low cadence, with AUTH perhaps having the biggest impact of them all under some workloads. The performance penalty of enabling just the AUTH category [has been measured](https://scylladb.atlassian.net/wiki/spaces/RND/pages/148308005/Audit+performance+impact+test) and while authentication throughput and read/write throughput remain stable, the queries' P99 latency may decrease by a couple of % in the most hardcore scenarios.

Fixes: https://github.com/scylladb/scylladb/issues/26020

Gradually re-enabling audit feature, no need to backport.

Closes scylladb/scylladb#27262

This repository contains the source files for ScyllaDB documentation.

  • The dev folder contains developer-oriented documentation related to the ScyllaDB code base. It is not published and is only available via GitHub.
  • All other folders and files contain user-oriented documentation related to ScyllaDB and are sources for docs.scylladb.com/manual.

To report a documentation bug or suggest an improvement, open an issue in GitHub issues for this project.

To contribute to the documentation, open a GitHub pull request.

Key Guidelines for Contributors

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

  1. Run make preview in the docs/ directory 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

If you are interested in contributing to Scylla docs, please read the Scylla open source page at http://www.scylladb.com/opensource/ and complete a Scylla contributor agreement if needed. We can only accept documentation pull requests if we have a contributor agreement on file for you.
