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/

Vol:17 No:11 → Robust Join Processing with Diamond Hardened Joins vldb.org/pvldb/vol17/p3…

For a high-level overview of how we achieve great OLAP and OLTP performance, you can also browse our blog post at cedardb.com/blog/colibri/. If you are at VLDB this year, don't miss Tobias' presentation ;)

Xiangpeng Hao strikes again: Turns out you can both 1. Implement 🇩🇪 strings in Rust 2. They actually improve end to end performance in ApacheDataFusion. It takes a lot more than a straightforward naive implementation to do so: influxdata.com/blog/faster-qu…

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…

Part 2 of how to use StringView / German Strings to *actually* make queries faster. Comparisons, inlining, gc, and buffer size tuning. influxdata.com/blog/faster-qu… Again all due to our incredible intern Xiangpeng Hao

Having data in memory is considered the gold standard for data analysis, but are you sure that RAM locality alone is enough? Read on to learn about the new king of efficient data processing: cedardb.com/blog/reducing_…

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…

How hard can summing up numbers be? ➕ 🔢 It turns out that correctly calculating the sum of integers has more pitfalls than you might expect! Read our latest blog post for details: cedardb.com/blog/overflow_…

Have you ever wondered why you see the last entry again when switching to the second page of a website? The culprit is "offset"! Read why in our blog post and find out what to use instead. cedardb.com/blog/paginatio…

You don’t need an army of C++ devs to hand-optimize every query. We let the code write the code. Read our latest blog post to see how we mix runtime flexibility with almost magical performance! cedardb.com/blog/compilati…

CedarDB (hot new Postgres-compatible database out of TUM) launched a free community edition last week and Justin took it for a spin. Good read.

Congratulations to SortMergeJoins from TU Munich - winners of the 2025 SIGMOD Programming Contest! Built by the Umbra research group (CedarDB’s roots), their system ran 12× faster than median - entirely open-source and no sort-merge-joins to be found 😉: github.com/umbra-db/conte…

Next episode(releasing soon) is another banger on The GeekNarrator. CedarDB with Philipp Fent We go really deep into the architecture, data structures, analytics, query optimisation and so on. In case you missed the latest banger on Uni kernels check this out: You don't

Just released another episode in the "Modern Database" Playlist which has 45+ database episodes. This time we are talking to Philipp Fent from CedarDB about #CedarDB and learning about the innovations and the amazing engineering behind this modern ultra fast database. Key

What if a database could be your game engine? During parental leave Lukas Vogel built DOOMQL: A multiplayer DOOM-like where everything (rendering, game loop, state) runs in pure SQL on CedarDB. It's fast, ridiculous, and surprisingly elegant. Full write-up: cedardb.com/blog/doomql
