title: Is there a native graph database extension for MySQL/MariaDB?
body: <p>I want to store some kind of my relational data into graphs. There are two options:</p>
  
  <ul>
  <li>Parent/Child</li>
  <li>Nested Sets</li>
  </ul>
  
  <p>Where Nested Sets are only useful for hierachical data, the Parent/Child model has a huge impact on performance, especially when querying large sets of nodes.</p>
  
  <p>I noticed, that MariaDB has a storage engine called OQGRAPH: <a href="https://mariadb.com/kb/en/library/oqgraph-storage-engine/" rel="nofollow noreferrer">https://mariadb.com/kb/en/library/oqgraph-storage-engine/</a>
  which seems to look as the best implementation of graphs for RDBMS.</p>
  
  <p>Are there more options known, or should I use Recursive Common Table Expressions (<a href="https://mariadb.com/kb/en/library/recursive-common-table-expressions-overview/" rel="nofollow noreferrer">https://mariadb.com/kb/en/library/recursive-common-table-expressions-overview/</a>)</p>
