But one paper that I considered is on the checkpoint algorithm in NDB, Partial Local Checkpoint. Haven't really seen any papers on incremental MainMemoryDB checkpoint algorithms. Probably because it is a really hard problem. Took 2.5 years to implement.

Yep, which formed the base for RonDB documentation docs.rondb.com. A colleague is working hard now to improve this docs and making it more pedagogic and extending it even further.

Welcome to a webinar today about J0927, Fastest Key Value Database at 15.00 CET, 9.00 EST. Replayed at 19.00 CET, 10.00 PT. hopsworks.ai/events/j0927-f…

For those that didn't have a chance to join the webinar on J0927, Fastest Key Value Database it is now available on youtube: youtube.com/watch?v=yDkINf…

Here is a good christmas reading, I am stacking reading material for the 2 weeks of Christmas we have in Sweden. Here is one thing I will read.

My colleague Vincent has spent some time improving the RonDB documentation. mikaelronstrom.blogspot.com/2024/01/major-…

I am very excited that Klaus Jensen from Samsung, along with a few of his colleagues, have agreed to join /r/databasedevelopment for an hour-long AMA on all things NVMe. To be held at the end of January. Klaus is maintainer of the QEMU emulated NVMe device and coauthor on a

Great news

Hopsworks Feature Store now supporting Multi-Region with failover between Regions using features in RonDB and Kafka: hopsworks.ai/post/multi-reg… hopsworks.ai/post/multi-reg…

Great article, there is also another method to get Grafana. github.com/logicalclocks/… gathers stuff into Prometheus. github.com/logicalclocks/… contains code for 11 dashboards in Grafana and triggers for some events as well.

Post on testing RonDB, quote from it: This makes it clear that building a DBMS and a data platform is very beneficial for the quality of the DBMS. mikaelronstrom.blogspot.com/2024/03/testin…

New LTS version of RonDB released for general availability (GA) today. RonDB 22.10.2 is integrated in Hopsworks 3.7 supporting LLMs, Machine Learning and Feature Stores. More details found in the blog. mikaelronstrom.blogspot.com/2024/03/new-lt…

The scan can even be a join of many tables with filtering on each table and getting data from one table in evaluating a later table

Visiting Cyprus but leave few hours before the event

In my view real-time usually means that there is a human user waiting for the result. In most cases this means responding in milliseconds unless the user is willing to wait for a longer time.

What I discovered when I implemented Query Threads with up to thousands of CPUs is that a single server is definitely a distributed systems where the concept of time is acutely visible.

Nice picture showing how NDB Cluster works and how RonDB 21.04 works. In RonDB 22.10.4 the query threads are replaced by query workers in LDM threads, Receive threads and TC threads and main thread and replication thread thus ensuring that all CPUs are effectively used. Gains 30%

I am leaving X (Twitter), it's become a disinformation site, so no use of trying to spread information here. LinkedIn is my choice of spreading technical information.
