I love these features it provides:&lt;/p&gt;
&lt;h4 id="high-performance"&gt;High Performance&lt;/h4&gt;
&lt;p&gt;According to to it&amp;rsquo;s &lt;a href="https://docs.influxdata.com/influxdb/v1.7/guides/hardware_sizing/#single-node-or-cluster" target="_blank" rel="noopener noreffer "&gt;hardware guide&lt;/a&gt;, a single node will support more than 750k point write per second, 100 moderate queries per second and 10M series cardinality.&lt;/p&gt;
&lt;h4 id="continuous-queries"&gt;Continuous Queries&lt;/h4&gt;
&lt;p&gt;Simple aggregation can be done by InfluxDB&amp;rsquo;s continuous queries.&lt;/p&gt;
&lt;h4 id="overwrite-duplicated-points"&gt;Overwrite Duplicated Points&lt;/h4&gt;
&lt;p&gt;If you submit a new point with same measurements, tag set and timestamp, the new data will overwrite the old one.&lt;/p&gt;</description></item></channel></rss>
