Show HN: RonDB – fast key-value database in the cloud

RonDB is the 3rd fork of MySQL (after PerconaDB and MariaDB). However, it is a fork of MySQL Cluster (NDB cluster database engine), not InnoDB. And this time, it's the inventor of the storage engine that is doing the forking. Mikael Ronstrom invented NDB Cluster, a distributed in-memory database, when he was a Ericsson in the late '90s and MySQL bought it off Ericsson in 2003 (or 2002?). Now, Mikael is working on a cloud-native distribution of NDB, RonDB, at Logical Clocks. NDB always had a reputation as high throughput, low latency, and difficult to configure/operate. RonDB is about fixing those flaws as a cloud native service.

&gt; world&#x27;s fastest key value store<p>Where can I see the data for this comparison? A quick search only brings up benchmarks of this db against itself on different VM setups, and the site doesn&#x27;t link such a thing from anywhere I&#x27;ve thought to look yet.

Too much marketing. Don’t get me wrong but I’m lost among “fast, scalable, low latency, high throughput” marketing paragraphs and images.<p>There are links to other websites(company website I guess), it is same unfortuanetely.<p>Please consider adding sections&#x2F;pages about “how did you do it, benchmarks supporting your claim, what is different in your product compared to ndb” etc. If there are links to these somewhere, you may want to make it more visible in your front page.

Some sysbench benchmark results are here comparing results on AWS, GCP, and Azure. Interesting to see AWS is better at lower low load (due to better interrupt handling in VMs?), while GCP is best at highest loads.<p><a href="http:&#x2F;&#x2F;mikaelronstrom.blogspot.com&#x2F;" rel="nofollow">http:&#x2F;&#x2F;mikaelronstrom.blogspot.com&#x2F;</a>

&gt; RonDB provides Class 6 Availability, meaning its system is operational 99.9999% of the time, thus no more than 30 seconds of downtime per year. This ensures that RonDB is always available.<p>I get marketers stretch the truth all the time, but they can&#x27;t possibly be serious.

Best wishes!<p>IMHO: Next step <a href="https:&#x2F;&#x2F;jepsen.io&#x2F;analyses" rel="nofollow">https:&#x2F;&#x2F;jepsen.io&#x2F;analyses</a> test

For comparison to other databases it should be pointed out that RonDB appears to only support &quot;read committed&quot; concurrency mode: <a href="https:&#x2F;&#x2F;docs.rondb.com&#x2F;rondb_concepts&#x2F;#consistency-models" rel="nofollow">https:&#x2F;&#x2F;docs.rondb.com&#x2F;rondb_concepts&#x2F;#consistency-models</a>. Most other &quot;modern&quot; databases these days (CockroachDB&#x2F;Spanner&#x2F;FoundationDB&#x2F;Yugabyte&#x2F;FaunaDB) are focusing on providing far stricter guarantees.

This blog post shares a little more information: <a href="https:&#x2F;&#x2F;www.logicalclocks.com&#x2F;blog&#x2F;rondb-21-04-0" rel="nofollow">https:&#x2F;&#x2F;www.logicalclocks.com&#x2F;blog&#x2F;rondb-21-04-0</a><p>And here are the docs: <a href="https:&#x2F;&#x2F;docs.rondb.com&#x2F;" rel="nofollow">https:&#x2F;&#x2F;docs.rondb.com&#x2F;</a>

How many nines will managed RonDB provide when running in public clouds?

What are you scarifying when going LATS? It sounds too good to be true.

I wonder how much it costs. I didn&#x27;t see pricing info on the website.<p>EDIT: I wonder how much the managed version costs.

are you sure the fastest? &#x27;__&#x27;) i thought fastest is aerospike, or if you need sql capability: tarantool
