We were surprised to find out that everybody uses our strings. They even call them "German Strings". 😲🇩🇪 Take a look at our latest blog post to find out why DuckDB, ApacheArrow, polars data, and Facebook Velox use our custom string implementation. cedardb.com/blog/german_st…

Our last post on our "German Strings" has received tremendous attention. This week, we follow up on some of your comments and dive deeper into the reasons behind some of our string optimizations: cedardb.com/blog/strings_d…

Last month, two of our co-founders (Moritz Sichert & Chris Winter) sat down with Timothy Chen and Ian Livingstone on the "Yet Another Infra Deep Dive" podcast, where they had the opportunity to discuss the current state of data processing and their vision for CedarDB. Give it a listen!

Have you ever wondered why existing database systems focus on either analytical or transactional performance? Learn why this is the case and how a hybrid storage engine can deliver high performance for combined workloads: cedardb.com/blog/colibri/

SQL is a declarative language. Still, many systems require writing hand-tune SQL to get the best performance. Learn what it takes to reclaim SQL's declarative power: cedardb.com/blog/unnest_sq…

Why old-school exceptions are still a good idea: They provide a better user and developer experience and are even faster than error values! Read more in our blog: cedardb.com/blog/exception…

While tape is still dead, are you sure that RAM locality is still king?

The underlying data layout of your program can either help or hurt your algorithms. In our latest post, we explore why optimizing the storage layout is the key to unlocking blazingly fast data processing. cedardb.com/blog/optimizin…
