It is a real conundrum. I&amp;#x27;ve been waiting patiently for something to show up, but the gap seems to keep getting bigger instead of smaller.&lt;p&gt;Is it that people want to make the problem more complex that it needs to be? Is it that those who know most about these issues don&amp;#x27;t share their secrets so implemented from the outside often don&amp;#x27;t have a good understanding of how to do things properly? If you were to asked the guy behind Prometheus if he&amp;#x27;s looked at the commercial offerings and what he&amp;#x27;s learned from them, would even be able to speak about them intelligently?&lt;p&gt;There seems to be a huge skills gap on these things that I can&amp;#x27;t put my finger on. I&amp;#x27;d love to be able to use a real TSDB, even at only half the speed and usefulness. It would be great for these smaller firms that cant or wont pay the license fees for a commercial offering until they get larger.</text><parent_chain></parent_chain></comment><story><title>Writing a Time Series Database from Scratch</title><url>https://fabxc.org/blog/2017-04-10-writing-a-tsdb</url></story>

It certainly seems like the good systems are converging on very similar storage architectures. This design is so similar to how Kafka and Kudu work internally.&lt;p&gt;As the raw storage seems pretty optimal now, I suspect next we&amp;#x27;ll see a comeback of indices for more precise queries to get another jump in performance.</text><parent_chain></parent_chain></comment><story><title>Writing a Time Series Database from Scratch</title><url>https://fabxc.org/blog/2017-04-10-writing-a-tsdb</url></story>
