It&amp;#x27;s the commercialization of the widely cited Umbra research DBMS [0] that has been in the works for several years, which benchmarks faster than DuckDB for OLAP [1] whilst simultaneously being really strong for transactional workloads. Also discussed recently here [2].&lt;p&gt;[0] &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;umbra-db.com&amp;#x2F;&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;umbra-db.com&amp;#x2F;&lt;/a&gt;&lt;p&gt;[1] &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;cedardb.com&amp;#x2F;blog&amp;#x2F;ode_to_postgres&amp;#x2F;&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;cedardb.com&amp;#x2F;blog&amp;#x2F;ode_to_postgres&amp;#x2F;&lt;/a&gt;&lt;p&gt;[2] &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;news.ycombinator.com&amp;#x2F;item?id=40241150&quot;&gt;https:&amp;#x2F;&amp;#x2F;news.ycombinator.com&amp;#x2F;item?id=40241150&lt;/a&gt;</text></comment>
