After a very thorough development and test period we are proud to announce the general availability of the RonDB 22.10 LTS serie with the release of RonDB 22.10.2 today. There is also a new version of the old LTS version RonDB 21.04.16 released today.
A complete list of the new features is provided in the RonDB Documentation.
The most important new feature is the support of variable sized disk rows. This means a very significant saving of disk space, up to 10x more data can be stored on the same disk space as with RonDB 21.04. In addition RonDB 22.10 contains a major quality improvement using disk columns. This means that RonDB is now prepared for the introduction of features in the Hopsworks Feature Store using disk columns. This will provide significant cost savings in storing lots of features in the Hopsworks Online Feature Store.
Another important feature in RonDB 22.10 is that all major data structures are now using the Global Data Manager, this ensures that the memory management inside RonDB is much more flexible. This was the final step of a long project described here.
As usual we have also been working on performance in this new version. Write throughput has been siginficantly improved, enterprise applications using read locks will see greater scalability and also throughput at very high load has been significantly improved leading to up to 30% better throughput in RonDB 22.10.2 compared to RonDB 21.04. This improvement comes from further improvements to ideas presented in this blog. This change makes it possible to be much more flexible in using CPU resources. More details on performance comes later.
In this blog we have described the testing process that we have had with RonDB. RonDB 22.10 is already running in production in a number of installations and is part of Hopsworks 3.7 released recently. This Hopsworks version introduces support of fine-tuning LLMs for GenAI. This version of Hopsworks also supports multi-region support.
Come to our webinar where we will present more information about RonDB and what it can be used for.
Since Oracle now made MySQL 8.0 an LTS version we plan to merge the changes from MySQL 8.0 series into future RonDB 22.10 versions. Bug fixes and features of interest to Oracle is contributed back to MySQL.
For those interested in following the development of RonDB in real-time the tree is here, the branch where RonDB 22.10.2 is found is called 22.10.1. The development branch of RonDB 22.10 is found in 22.10-main. We are also working on new features of RonDB in forks of this tree by the developers. 22.10-main already have a new feature supporting more than 20k table objects and an even more improved thread model providing an improvement of around 5% better throughput. There is also long-term development of rate limits and quotas, enabling RonDB to be used in multi-tenant environments and pushdown of aggregations, enabling a speedup of 10-1000x of some queries used in Feature Stores.
