Nevertheless, it works for ML use cases as well.</p> <p>The current release is the first release. We are planning many new features. If you would like to request features, or need help or advice, you may contact us at <a href="mailto:hello@open-diffix.org">hello@open-diffix.org</a>. You may also post bug reports or feature requests as GitHub issues at <a href="https://github.com/diffix/syndiffix" rel="external nofollow noopener" target="_blank">github.com/diffix/syndiffix</a>.</p> <h3 id="pg_diffix">pg_diffix</h3> <p><strong>pg_diffix</strong> is a PostgreSQL extension that gives aggregate anonymized answers to SQL queries. Advantages over <strong>SynDiffix</strong> include:</p> <ul> <li>Faster and more scalable</li> <li>Supports untrusted users</li> <li>Supports back-end data for applications</li> </ul> <p><strong>pg_diffix</strong> only returns aggregate answers (column values and associated counts) to a very limited subset of SQL. It is far less flexible than <strong>SynDiffix</strong>. See <a href="https://github.com/diffix/pg_diffix" rel="external nofollow noopener" target="_blank">github.com/diffix/pg_diffix</a>.</p> <p>Development on <strong>pg_diffix</strong> is currently paused.
