   Sadly I have to note, that almost all modern DBMS companies don’t bring anything new to the table. They incredibly over-funded, but compete in S&M instead of R&D. A sizable chunk of those are essentially Postgres over RocksDB. Don’t

   That is hilarious. For reference, Sun acquired MySQL AB in February 2008 for $1 billion.

   Yeah, saw it, but never tried. Java, C# and other high level languages have libraries for basic SIMD operations. It's completely different world from manually invoking intrinsics in C or writing raw assembly. I am wondering where WASM

   Sure, electromagnetic waveband is exactly what I meant, just phrased it in more accessible terms. AP is my academical background. I didn't think I could contribute much there, so I quit even before LIGO was constructed. Now it looks in

   I am surprised there is no isolation schema for binaries. WASM may look lite and fast compared to Docker, but its still painfully slow compared to AVX or Neon enabled assembly. We went from VMs to Containers. From Containers to WASM. Now, I

   Can’t wait to see what Astrophysics and Cosmology will look like in 20 years. Just a decade ago we were bound to the radio spectrum and had 0 experience with gravitational waves…

   Wow! I was working on this issue in our DBMS product today! Fun suggestion, try making a JSON string with a NULL character somewhere in the middle. It will be encoded as \u0000 and is a a valid UTF-8 code, but most C based systems will trun

    Thanks for sharing! Its so frustrating that modern banks are split into two distinct categories: the classical banks and the neo-banks. The first ones are slow, ugly and borderline unusable. The latter ones are sleek and fast, but completel

    Thanks! It was on the longer list of smaller DBMS brands, but I was afraid to make the volume incomprehensible. Maybe we will write a more focused version, covering just smaller startups in 2022.

    Thanks a lot! I have never worked with RethinkDB specifically, but I can assure you - it's only one of many names in the DBMS graveyard. Most have probably died because of inability to monetize open-source software. For DBMS startups,

    Maybe not exactly the same bubble, but it's hard not to make parallels. Pets.com, one of the most comical cases of 2000s, was worth $400M at peak. When Chewy.com went public, they dwarfed that number with a new record of $13B. The anal

    Sure, you can configure a cheaper server with just the hardware needed for this benchmark, this is just the fastest machine we have in our cluster RAM-wise, that has one NUMA node. That's why we added it as an extra point of reference.

    This benchmark isn’t single threaded, it utilizes all the physical cores found in the machine, 64 on Threadripper and 10 on Mac. See the source for details: https://github.com/unum-cloud/HashTableBenchmark/blob&#x2

    Haha, those numbers are outrageous) We are now streaming about 50 GB/s from our persistent storage on each machine. At those rates even a single memcpy will be noticeable, so we are forced to disable OS page caching and often bypass th
